Exercise 7 Page 27

Use the Quotient of Powers Law. This Law states that to divide powers with the same base, we need to subtract their exponents.

27x^2

Practice makes perfect

We want to simplify the rational expression by using the Laws of Exponents. 3^4x^4/3x^2 In this case, we will use the Quotient of Powers Law. This Law states that to divide powers with the same base, we need to subtract their exponents. Let's do it!

3^4x^4/3x^2

Write as a product of fractions

3^4/3 * x^4/x^2

a=a^1

3^4/3^1 * x^4/x^2

a^m/a^n= a^(m-n)

3^(4-1) * x^(4 - 2)

Subtract term

3^3 * x^2

Calculate power

27x^2
