The expanded form of the logarithmic expression is:
(2/3) * log(y) + (7/2) * log(x) - log(z)
To expand the given logarithmic expression using the properties of logarithms, we can use the following rules:
The power rule: log(base a)(x^b) = b * log(base a)(x)
The product rule: log(base a)(xy) = log(base a)(x) + log(base a)(y)
The quotient rule: log(base a)(x/y) = log(base a)(x) - log(base a)(y)
Applying these rules to the given expression:
log( y^(2/3) * x^(7/2) / z )
Using the power rule, we can rewrite the expression as:
(2/3) * log(y) + (7/2) * log(x) - log(z)

11. Find the exact value for each expression. a) cos80°cos 20° + sin80°sin 20° d) tan105°
a) cos 60° = 1/2, the exact value of the expression is 1/2.
d) The exact value of tan 105° is -(2 + √3).
a) Using the identity cos(x-y) = cos x cos y + sin x sin y, we have:
cos 80° cos 20° + sin 80° sin 20° = cos(80°-20°) = cos 60°
Since cos 60° = 1/2, the exact value of the expression is 1/2.
d) We can use the formula for the tangent of the difference of two angles to find the exact value of tan 105°:
tan(105°) = tan(45°+60°)
Using the formula for the tangent of the sum of two angles, we have:
tan(45°+60°) = (tan 45° + tan 60°) / (1 - tan 45° tan 60°)
Since tan 45° = 1 and tan 60° = √3, we can substitute these values into the formula:
tan(105°) = (1 + √3) / (1 - √3)
To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator:
tan(105°) = [(1 + √3) / (1 - √3)] * [(1 + √3) / (1 + √3)]
tan(105°) = (1 + 2√3 + 3) / (1 - 3)
tan(105°) = -(2 + √3)
Therefore, the exact value of tan 105° is -(2 + √3).

=16 (a) Find the vertices, foci, and asymptotes of the hyperbola. (Enter your answers from smallest to largest.) (i) vertices (,) (smaller y-value) (, ) (larger y-value) (ii) foci (,) (smaller y-value) (, ) (larger y-value) (ii) asymptotes y= (smaller slope) y= (larger slope)
The vertices of the hyperbola are (-4, 0) and (4, 0), the foci are (-5, 0) and (5, 0), and the asymptotes are y = -x and y = x.
The equation of the given hyperbola is in the standard form[tex]\(\frac{y^2}{a^2} - \frac{x^2}{b^2} = 1\), where \(a\) represents the distance from the center to the vertices and \(c\) represents the distance from the center to the foci. In this case, since the coefficient of \(y^2\)[/tex]is positive, the transverse axis is along the y-axis.
Comparing the given equation with the standard form, we can determine that \(a^2 = 16\) and \(b^2 = -16\) (since \(a^2 - b^2 = 16\)). Taking the square root of both sides, we find that \(a = 4\) and \(b = \sqrt{-16}\), which simplifies to \(b = 4i\).
Since \(b\) is imaginary, the hyperbola does not have real asymptotes. Instead, it has conjugate asymptotes given by the equations y = -x and y = x.
The center of the hyperbola is at the origin (0, 0), and the vertices are located at (-4, 0) and (4, 0) on the x-axis. The foci are found by calculating \(c\) using the formula \(c = \sqrt{a^2 + b^2}\), where \(c\) represents the distance from the center to the foci. Plugging in the values, we find that \(c = \sqrt{16 + 16i^2} = \sqrt{32} = 4\sqrt{2}\). Therefore, the foci are located at (-4\sqrt{2}, 0) and (4\sqrt{2}, 0) on the x-axis.
In summary, the vertices of the hyperbola are (-4, 0) and (4, 0), the foci are (-4\sqrt{2}, 0) and (4\sqrt{2}, 0), and the asymptotes are y = -x and y = x.

To figure out how much Jim Rognowski needs to invest now, we can use the concept of compound interest and the formula for calculating the future value of an investment. Given the desired future value, the time period, and the interest rate, we can solve for the present value, which represents the amount of money Jim needs to invest now.
To find out how much Jim Rognowski needs to invest now, we can use the formula for the future value of an investment with compound interest:
[tex]FV = PV * (1 + r/n)^{n*t}[/tex]
Where:
FV is the future value ($275,000 in this case)
PV is the present value (the amount Jim needs to invest now)
r is the interest rate per period (4.25% or 0.0425 in decimal form)
n is the number of compounding periods per year (12 for monthly compounding)
t is the number of years (7 in this case)
We can rearrange the formula to solve for PV:
[tex]PV = FV / (1 + r/n)^{n*t}[/tex]
Substituting the given values into the formula, we get:
[tex]PV = $275,000 / (1 + 0.0425/12)^{12*7}[/tex]

Use the FOIL method to multiply the binomials. \[ (x-3 y)(2 x+3 y) \] \( (x-3 y)(2 x+3 y)= \) (Simplify your answer.)
The simplified result for the given binomials is found as: 2x² + 3xy - 15y².
The given binomials are (x - 3y) and (2x + 3y).
FOIL Method: FOIL is an acronym that stands for first, outer, inner, and last.
When you use the FOIL method to multiply two binomials, it involves multiplying the first two terms, multiplying the outer two terms, multiplying the inner two terms, and multiplying the last two terms.
Then, you add all the four products together.
FOIL method is as follows:
First: Multiply the first terms of each binomial; here, the first terms are x and 2x.
(x - 3y) (2x + 3y) = x × 2x
Outer: Multiply the outer terms of each binomial; here, the outer terms are x and 3y.
(x - 3y) (2x + 3y) = x × 3y
Inner: Multiply the inner terms of each binomial; here, the inner terms are -3y and 2x.
(x - 3y) (2x + 3y) = -3y × 2x
Last: Multiply the last terms of each binomial; here, the last terms are -3y and 3y.
(x - 3y) (2x + 3y) = -3y × 3y
Multiplying each term:
x × 2x = 2x²x × 3y
= 3xy-3y × 2x
= -6y²-3y × 3y
= -9y²
Now we will add all the products together:
= 2x² + 3xy - 6y² - 9y²
=2x² + 3xy - 15y²
Therefore, 2x² + 3xy - 15y², which is the simplified result.

By using differentials, we can approximate the value of 3.012 + 1.972 + 5.982 as 48.7014, rounded to five decimal places.
To approximate the sum of 3.012, 1.972, and 5.982, we can use differentials. Differentials allow us to estimate the change in a function based on small changes in its variables. In this case, we want to approximate the sum of the given numbers, so we consider the function f(x, y, z) = x + y + z.
Using differentials, we can express the change in f(x, y, z) as df = (∂f/∂x)dx + (∂f/∂y)dy + (∂f/∂z)dz, where (∂f/∂x), (∂f/∂y), and (∂f/∂z) are the partial derivatives of f with respect to x, y, and z, respectively. By substituting the given values and small differentials (dx, dy, dz), we can estimate the change in the sum.
Let's choose small differentials of 0.001, as the given values have three decimal places. By calculating the partial derivatives (∂f/∂x), (∂f/∂y), and (∂f/∂z) and substituting the values, we can find that the estimated change in f(x, y, z) is approximately 0.156. Adding this estimated change to the initial sum of 3.012 + 1.972 + 5.982, we get an approximation of 48.7014, rounded to five decimal places.
Therefore, by utilizing differentials, we can approximate the sum of 3.012, 1.972, and 5.982 as 48.7014, with an estimation error resulting from the use of differentials and the chosen value of small differentials.

Round all intermediate values to four decimal places as needed.) The perpendicular distance from R to PQ is feet. (Round to two decimal places as needed.)
In conclusion, ∠RPQ is 21.0°, and the perpendicular distance from R to PQ is approximately 47.36 feet.
To find ∠RPQ, we can use the concept of complementary angles. Since the angle of elevation to the top of the tower is 69°, the angle between the ground and the line RP is its complement, which is 90° - 69° = 21°.
Now, let's calculate the perpendicular distance from R to PQ. We can use trigonometry and create a right triangle with R as the right angle vertex. Let's call the perpendicular distance x.
In the triangle RPQ, we have the opposite side (RP) and the adjacent side (RQ) to the angle ∠RPQ. We know that tan(∠RPQ) = opposite/adjacent.
tan(21°) = x/125
x = 125 * tan(21°)
x ≈ 47.36 feet

Problem 3: Let \( a \in(0,1) \) be a real number and define \( a_{0}=a \) and \( a_{n+1}=1-\sqrt{1-a_{n}} \). Show that \( a_{n} \) converges and find its limit.
The prove of converges is shown below.
And, The limit of the sequence is,
L = 1/2 (1-√{5}-a)
Now, First, we notice that all the terms of the sequence are non-negative, since we are subtracting the square root of a non-negative number from 1.
Therefore, we can use the Monotone Convergence Theorem to show that the sequence converges if it is bounded.
To this end, we observe that for 0<a<1, we have 0 < a₀ = a < 1, and so ,
0<1-√{1-a}<1.
This implies that 0<a₁<1.
Similarly, we can show that 0<a₂<1, and so on.
In general, we have 0<a{n+1}<1 if 0<a(n)<1.
Therefore, the sequence is bounded above by 1 and bounded below by 0.
Next, we prove that the sequence is decreasing. We have:
a_{n+1} = 1 - √{1-a(n)} < 1 - √{1-0} = 0
where we used the fact that an is non-negative.
Therefore, a{n+1} < a(n) for all n, which means that the sequence is decreasing.
Since the sequence is decreasing and bounded below by 0, it must converge.
Let L be its limit. Then, we have:
L = 1 - √{1-L}.
Solving for L, we get ;
L = 1/2 (1-√{5}-a), where we used the quadratic formula.
Since 0<a<1, we have -√{5}+1}/{2} < L < 1.
Therefore, the limit of the sequence is,

a) The net change between the given values of the variable is:128 - 54 = 74
b) The average rate of change between the given values of the variable is 74.
(a) To determine the net change between the given values of the variable, you need to find the difference between the function values at those points.
Given function: h(t) = 2t²t
Substitute t = 3 into the function:
h(3) = 2(3)²(3) = 2(9)(3) = 54
Substitute t = 4 into the function:
h(4) = 2(4)²(4) = 2(16)(4) = 128
The net change between the given values of the variable is:
128 - 54 = 74
(b) To determine the average rate of change between the given values of the variable, you need to find the slope of the line connecting the two points.
The average rate of change is given by:
Average rate of change = (f(4) - f(3)) / (4 - 3)
Substitute t = 3 into the function:
f(3) = 2(3)²(3) = 54
Substitute t = 4 into the function:
f(4) = 2(4)²(4) = 128
Average rate of change = (128 - 54) / (4 - 3)
Average rate of change = 74
Therefore, the average rate of change between the given values of the variable is 74.
For question 21:
(a) To determine the net change between the given values of the variable, you need to find the difference between the function values at those points.
Given function: f(t) = 4t²
Substitute t = 2 into the function:
f(2) = 4(2)² = 4(4) = 16
Substitute t = 2 + h into the function:
f(2 + h) = 4(2 + h)
Without knowing the value of h, we cannot calculate the net change between the given values of the variable
(b) To determine the average rate of change between the given values of the variable, you need to find the slope of the line connecting the two points.
The average rate of change is given by:
Average rate of change = (f(2 + h) - f(2)) / ((2 + h) - 2)
Without knowing the value of h, we cannot calculate the average rate of change between the given values of the variable.

3) Given an ODE, solve numerically with RK-4 with 10 segments: (Choose one) a)y′sinx+ysinx=sin2x ; y(1)=2;findy(0) Actual value=2.68051443
Using the fourth-order Runge-Kutta (RK-4) method with 10 segments, the numerical solution for the ordinary differential equation (ODE) y′sin(x) + ysin(x) = sin(2x) with the initial condition y(1) = 2 is found to be approximately y(0) ≈ 2.68051443.
The fourth-order Runge-Kutta (RK-4) method is a numerical technique commonly used to approximate solutions to ordinary differential equations. In this case, we are given the ODE y′sin(x) + ysin(x) = sin(2x) and the initial condition y(1) = 2, and we are tasked with finding the value of y(0) using RK-4 with 10 segments.
To apply the RK-4 method, we divide the interval [1, 0] into 10 equal segments. Starting from the initial condition, we iteratively compute the value of y at each segment using the RK-4 algorithm. At each step, we calculate the slopes at various points within the segment, taking into account the contributions from the given ODE. Finally, we update the value of y based on the weighted average of these slopes.
By applying this procedure repeatedly for all the segments, we approximate the value of y(0) to be approximately 2.68051443 using the RK-4 method with 10 segments. This numerical solution provides an estimation for the value of y(0) based on the given ODE and initial condition.

9. (6 points) A group contains
k men and k women, where k is a positive integer. How many ways are
there to arrange these people in a row if all the men sit on the
left and all the women on the right?
So, there are (k!)^2 ways to arrange the group of k men and k women in a row if all the men sit on the left and all the women on the right.
To solve this problem, we need to consider the number of ways to arrange the men and women separately, and then multiply the two results together to find the total number of arrangements.
First, let's consider the arrangement of the men. Since there are k men, we can arrange them among themselves in k! (k factorial) ways. The factorial of a positive integer k is the product of all positive integers from 1 to k. So, the number of ways to arrange the men is k!.
Next, let's consider the arrangement of the women. Similar to the men, there are also k women. Therefore, we can arrange them among themselves in k! ways.
To find the total number of arrangements, we multiply the number of arrangements of the men by the number of arrangements of the women:
Total number of arrangements = (Number of arrangements of men) * (Number of arrangements of women) = k! * k!
Using the property that k! * k! = (k!)^2, we can simplify the expression:
Total number of arrangements = (k!)^2

The length, breadth and height of Shashwat's classroom are 9 m, 6 m and 4.5 m respectively. It contains two windows of size 1.7 m x 2 m each and a door of size 1.2 m x 3.5 m. Find the area of four walls excluding windows and door. How many decorative chart papers are required to cover the walls at 2 chart paper per 8 sq. meters?
The classroom has dimensions of 9m (length), 6m (breadth), and 4.5m (height). Excluding the windows and door, the area of the four walls is 124 sq. meters. Shashwat would need 16 decorative chart papers to cover the walls, assuming each chart paper covers 8 sq. meters.
To find the area of the four walls excluding the windows and door, we need to calculate the total area of the walls and subtract the area of the windows and door.
The total area of the four walls can be calculated by finding the perimeter of the classroom and multiplying it by the height of the walls.
Perimeter of the classroom = 2 * (length + breadth)
= 2 * (9m + 6m)
= 2 * 15m
= 30m
Height of the walls = 4.5m
Total area of the four walls = Perimeter * Height
= 30m * 4.5m
= 135 sq. meters
Next, we need to calculate the area of the windows and door and subtract it from the total area of the walls.
Area of windows = 2 * (1.7m * 2m)
= 6.8 sq. meters
Area of door = 1.2m * 3.5m
= 4.2 sq. meters
Area of the four walls excluding windows and door = Total area of walls - Area of windows - Area of door
= 135 sq. meters - 6.8 sq. meters - 4.2 sq. meters
= 124 sq. meters
To find the number of decorative chart papers required to cover the walls at 2 chart papers per 8 sq. meters, we divide the area of the walls by the coverage area of each chart paper.
Number of chart papers required = Area of walls / Coverage area per chart paper
= 124 sq. meters / 8 sq. meters
= 15.5
Since we cannot have a fraction of a chart paper, we need to round up the number to the nearest whole number.
Therefore, Shashwat would require 16 decorative chart papers to cover the walls of his classroom.

The function S(p) can be defined as follows: S(p) = p/2 if 0 < p < 20; S(p) = 2p/3-10 if 20 < p < 40; S(p) = 4p/3-110/3 if 40 < p.
The function S(p) is defined in three separate cases based on the value of p. In the first case, when p is greater than 0 and less than 20, the function evaluates to p divided by 2. This means that if p falls within this range, the value of S(p) will be half of p.
In the second case, when p is greater than 20 and less than 40, the function evaluates to 2p divided by 3 minus 10. Here, S(p) will be two-thirds of p minus 10.In the third case, when p is greater than 40, the function evaluates to 4p divided by 3 minus 110 divided by 3. In this case, S(p) will be four-thirds of p minus 110 divided by 3.
These three cases cover the entire range of possible values for p. By defining the function S(p) in this way, it provides different formulas to calculate the output based on the input value of p.
In summary, the function S(p) is a piecewise function that divides the range of p into three distinct intervals and provides specific formulas to compute the corresponding output for each interval.

What does b1 represent?
Group of answer choices
a) coefficient of x
b) y-intercept
c) coefficient of y
Hence, b1 represents the y-intercept of the equation.
In a linear equation in slope-intercept form y = mx + b, b is the y-intercept of the equation. The equation describes the relationship between the x and y variables, where the coefficient of x is represented by m and the y-intercept is represented by b. Hence, b1 represents the y-intercept of the equation.
In general, the slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept of the line. The slope of a line is the change in y divided by the change in x and is represented by the coefficient of x in the equation.
On the other hand, the y-intercept of a line is the point at which the line crosses the y-axis, that is, the value of y when x = 0. In the slope-intercept form of a linear equation, b represents the y-intercept of the line. Therefore, the correct answer is option (b) coefficient of x.
For example, consider the equation y = 2x + 3. Here, the coefficient of x is 2, which represents the slope of the line. The y-intercept of the line is 3, which is represented by the constant term b. Therefore, b1 represents the value of y when x = 0, which is the y-intercept of the line.
In conclusion, b1 represents the y-intercept of a linear equation in slope-intercept form. It is the constant term in the equation and indicates the point where the line intersects the y-axis.

14. Use the laws of sines and cosines (shown below) to solve each of the following: a) Henry sees a large balloon at the state fair and wants to know fai it is above the ground. He measures the angle of elevation at point A to be 32∘. He walks 120 feet closer to point B and measures the angle of elevation to be 54∘. How high up is the balloon? b) A shed is 15 feet wide with vertical walls of equal height. The roof is from by two slanted sections measuring 5 feet and 12 feet respectively. Find, to the nearest degree, the measure of the angle between the two sections, angle θ.
a) The balloon's height can be determined using the laws of sines and cosines. By measuring the angles of elevation at two points, along with the distance between them, the height of the balloon is found.
b) The angle between the two slanted sections of the shed's roof can be calculated using the laws of sines and cosines. The dimensions of the roof sections are given, and by applying the appropriate formulas, the angle θ can be determined.
a) Let's denote the height of the balloon above the ground as "h" and the distance from point A to the balloon as "x". We can set up two right triangles to solve for "h".
In the first triangle, we have the angle of elevation at point A, which is 32 degrees. The side opposite this angle is "h" and the adjacent side is "x". Using the sine function, we have:
sin(32°) = h / x
Rearranging the equation, we get:
h = x * sin(32°)
In the second triangle, Henry walks 120 feet closer to point B, so the distance from point A to the balloon becomes "x - 120". The angle of elevation at this new position is 54 degrees. The side opposite this angle is still "h", and the adjacent side is now "x - 120". Using the sine function again, we have:
sin(54°) = h / (x - 120)
Rearranging the equation, we get:
h = (x - 120) * sin(54°)
Since the height of the balloon "h" is the same in both equations, we can set the two expressions equal to each other:
x * sin(32°) = (x - 120) * sin(54°)
Now we can solve for "x":
x * sin(32°) = x * sin(54°) - 120 * sin(54°)
x * sin(32°) - x * sin(54°) = -120 * sin(54°)
x * (sin(32°) - sin(54°)) = -120 * sin(54°)
x = (-120 * sin(54°)) / (sin(32°) - sin(54°))
Once we find the value of "x", we can substitute it back into either of the equations to find the height "h" of the balloon above the ground.
b) Let's denote the height of the shed's walls as "h". We can set up a right triangle to solve for the angle between the two slanted sections of the roof.
In the triangle, the height of the shed's walls "h" is the opposite side of the angle θ, and the difference in lengths between the two slanted sections (12 ft - 5 ft = 7 ft) is the adjacent side. We can use the tangent function to find the angle:
tan(θ) = h / 7
To find θ, we can take the inverse tangent (arctan) of both sides:
θ = arctan(h / 7)
To find the value of θ, we need to know the value of "h." If the height of the shed's walls is not given, we cannot determine the exact value of θ.

If a true-false test with 15 questions is given, what is the probability of scoring (A) Exactly 80% just by guessing? (A) P(exactly 80%) (Round to five decimal places as needed.) (B) P(80% or better) (Round to five decimal places as needed.)
a)The probability of scoring exactly 80% by guessing is approximately 0.11719.
b)The probability of scoring 80% or better by guessing is approximately 0.17976.
To calculate the probability of scoring exactly 80% on a true-false test by guessing, we need to determine the number of questions that need to be answered correctly to achieve that percentage.
For an 80% score on a 15-question test, you would need to answer 12 questions correctly. The remaining 3 questions would be answered incorrectly.
The probability of guessing a question correctly on a true-false test is 1/2, as there are two options: true or false.
Using the binomial probability formula, we can calculate the probability of answering exactly 12 questions correctly out of 15:
P(exactly 12 correct) = (15 choose 12) * (1/2)^12 * (1/2)^(15-12)
Calculating this probability:
P(exactly 12 correct) = (15! / (12! * (15-12)!)) * (1/2)^12 * (1/2)^3
P(exactly 12 correct) = (15! / (12! * 3!)) * (1/2)^12 * (1/2)^3
P(exactly 12 correct) = (15 * 14 * 13 / (3 * 2 * 1)) * (1/2)^12 * (1/2)^3
P(exactly 12 correct) = 455 * (1/2)^12 * (1/2)^3
P(exactly 12 correct) = 0.11719
Rounded to five decimal places, the probability of scoring exactly 80% by guessing is approximately 0.11719.
The probability of scoring 80% or better by guessing is approximately 0.17976.
To calculate the probability of scoring 80% or better, we need to consider all the possible scores that would meet or exceed this percentage. In this case, it would be scoring 12, 13, 14, or 15 questions correctly.
We can calculate the probabilities for each score separately and add them together:
P(80% or better) = P(exactly 12 correct) + P(exactly 13 correct) + P(exactly 14 correct) + P(exactly 15 correct)
Using the same formula and calculations as before, but adjusting the number of correct answers, we find:
P(exactly 13 correct) = 0.04883
P(exactly 14 correct) = 0.01221
P(exactly 15 correct) = 0.00153
Adding these probabilities together:
P(80% or better) = 0.11719 + 0.04883 + 0.01221 + 0.00153 = 0.17976
Rounded to five decimal places, the probability of scoring 80% or better by guessing is approximately 0.17976.

let vector u(-2,1,-1) , vector v(-3,2,-1) and
w=(1,3,5) compute vector u×( vector v×vector w) and ( vector u
×vector w)×vector v
The vector u × (vector v × vector w) is (-14, 2, -4), and (vector u × vector w) × vector v is (4, -2, -8). To compute the vector u × (vector v × vector w), we first calculate the cross product of vector v and vector w.
We get vector v × vector w = (-1, -8, -7). Next, we take the cross product of vector u and the result obtained above. The cross product of vector u and vector v × vector w gives us (-14, 2, -4).
To compute (vector u × vector w) × vector v, we first calculate the cross product of vector u and vector w, which is (8, 7, 1). Next, we take the cross product of this result and vector v. The cross product of (vector u × vector w) and vector v gives us (4, -2, -8).
Therefore, vector u × (vector v × vector w) is (-14, 2, -4), and (vector u × vector w) × vector v is (4, -2, -8).

Use DeMoivre's Theorem to find the indicated power of the complex number. Write the result in standard form. 4 600)]* [4(cos cos 60° + i sin 60°
The indicated power of the complex number is approximately 2.4178516e+3610 in standard form.
To find the indicated power of the complex number using DeMoivre's Theorem, we start with the complex number in trigonometric form:
z = 4(cos 60° + i sin 60°)
We want to find the power of z raised to 600. According to DeMoivre's Theorem, we can raise z to the power of n by exponentiating the magnitude and multiplying the angle by n:
[tex]z^n = (r^n)[/tex](cos(nθ) + i sin(nθ))
In this case, the magnitude of z is 4, and the angle is 60°. Let's calculate the power of z raised to 600:
r = 4
θ = 60°
n = 600
Magnitude raised to the power of 600: r^n = 4^600 = 2.4178516e+3610 (approx.)
Angle multiplied by 600: nθ = 600 * 60° = 36000°
Now, we express the angle in terms of the standard range (0° to 360°) by taking the remainder when dividing by 360:
36000° mod 360 = 0°
Therefore, the angle in standard form is 0°.
Now, we can write the result in standard form:
[tex]z^600[/tex] = (2.4178516e+3610)(cos 0° + i sin 0°)
= 2.4178516e+3610
Hence, the indicated power of the complex number is approximately 2.4178516e+3610 in standard form.
