Usando el método de índices
3 / √3 = 3¹ / 3¹ / ²
= 3¹ / 3⁰.⁵
= 3¹⁻¹ / ²
= 3 ¹ / ²
= √3
Esto también se puede resolver multiplicando tanto el numerador como el denominador por √3
3 / √3 * √3 / √3

Step-by-step explanation:
Use FOIL here.
Combine the first terms of both expressions.
5 * 5 = 25
Combine the outer terms of both expressions.
2x^4 * 5 = 10x^4
Combine the inner terms of both expressions.
-2x^4 * 5 = -10x^4
Combine the last terms of both expressions.
-2x^4 * 2x^4 = -4x^8
(a^x * a^y = a^(x+y).)
Now add those terms.
25 + 10x^4 - 10x^4 - 4x^8

Walter needs new grass in the circular pen for his chickens. The pen has 308 feet of fencing. What is the area of the pen?
Answers
Answer: 7546feet²
Step-by-step explanation:
Since the pen has 308 feet of fencing, this is the perimeter of the circular pen and we can get the raduus which goes thus:
Circumference of a circle = 2πr
2πr = 308
2 × 22/7 × r = 308
44/7 × r = 308
r = 308 × 7/44
r = 49
Therefore, area of the circular pen will be:
= πr²
= 22/7 × 49 × 49
= 7546feet²

Find the area of the circle below, to the nearest tenth. Use 3.14 for t.
Answers
Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
[tex]A=\pi r^2[/tex] ...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.
[tex]r=\dfrac{9}{2}[/tex]
[tex]r=4.5[/tex]
Substituting [tex]r=4.5, \pi =3.14[/tex] in (i), we get
[tex]A=(3.14)(4.5)^2[/tex]
[tex]A=(3.14)(20.25)[/tex]
[tex]A=63.585[/tex]
[tex]A\approx 63.6[/tex]
Therefore, the area of the given circle is 63.6.

Answer:
The formula for the area of the triangle is:
[tex]\displaystyle A=24x^2[/tex]
When x = 3, the area is 216 square centimeters.
When x = 2.4, the area is 138.24 square centimeters.
And when x = 5, the hypotenuse of the triangle is 50 centimeters.
Step-by-step explanation:
We are given a right triangle with a height of 8x and a base of 6x.
The area of a triangle is given by the formula:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
So, by substitution:
[tex]\displaystyle A=\frac{1}{2}(8x)(6x)=24x^2[/tex]
When x = 3, the area will be:
[tex]\displaystyle A(3)=24(3)^2=216\text{ cm}^2[/tex]
And when x = 2.4, the area will be:
[tex]A(2.4)=24(2.4)^2=138.24\text{ cm}^2[/tex]
When x = 5, the height will be 8(5) = 40 cm and the base will be 6(5) = 30 cm.
By the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
So:
[tex](40)^2+(30)^2=c^2[/tex]
The hypotenuse will be:
[tex]c=\sqrt{1600+900}=\sqrt{2500}=50\text{ cm}[/tex]
Which of the following steps would you perform to the system of equations below so that the equations have equal x coefficients? 4x+2y=4 12x+y=22 A. Multiply both sides of the top equation by 3 B. Divide both sides of the top equation by 3 C. Divide both sides of the bottom equation by 2 D. Multiply both sides of the bottom equation by 3
Answers
Explanation:
By multiplying the top equation by 3, you now have
12x + 6y = 12
12x + y = 22
To completely solve the equation, you multiply the whole bottom equation by -1.
12x + 6y = 12
-12x - y = -22
The -12x and 12 x cancel each other out.
6y = 12
-y = -22
______
5y = -10
y = -2
Now that you have the value of y, you can plug it into the original equation.
4x + 2y = 4
4x + 2(-2) = 4
4x - 4 = 4
4x = 8
x = 2
So, your final answer is (2, -2).
