What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ 7⁻² · 7⁵ · 7⁻³

Simplify the expression, then we have

⇒ 7⁻² · 7⁵ · 7⁻³

⇒ 7⁵ · 7⁻⁵

⇒ 7⁵ / 7⁵

⇒ 1

The value of the expression 7⁻² · 7⁵ · 7⁻³ will be 1. Then the correct option is B.

Answers

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

[tex]15^{2} +x^{2}=24^{2}[/tex]

Then you square the numbers that you currently have:

[tex]225+x^{2}=576[/tex]

Then subtract 225 from both sides to isolate the x:

[tex]x^{2} =576-225[/tex]

This gives you the equation:

[tex]x^{2} =351[/tex]

Then take the square root of both sides which gives you:

[tex]x=18.7349939952[/tex]

Then round to the nearest whole number which gives you x=19

The simplification of expression [tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]  is  [tex]x^{5}y^{2}[/tex].

SimplificationWhat is simplification?

Finding a solution to a complicated calculation that may involve square roots, cube roots, plus and minus integers, division, multiplication, and other mathematical operations is typically referred to as simplification.

What is exponent?

The number of times a number has been multiplied by itself is referred to as an exponent.

Rule of exponents:

Rule of the product of powers: When multiplying like bases, add the powers together.

Rule of the quotient of powers: When splitting like bases, take the powers out.

Solution for the expression:

The expression is given as

[tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]

Applying multiplication and product rule, one power of x will be reduced and 2 power of y will be reduced.

Thus, the the simplified equation will become [tex]x^{5}y^{2}[/tex].

Let's simplify the expression,

→ -4a + 14 + 7a - 9
