Question

Simplifying inside parentheses first pt. 2

Answer 1

The answer to your question is the second option

Explanation:

Process

Simplify using exponents laws, first inside the parentheses and then outside the parentheses.

`[(a^(-2)b^(2))/(a^(2)b^(-1)) ]^(-3)`

a) Simplify a

a⁻² a⁻² = a⁻⁴

b) Simplify b

b² b¹ = b³

c) Write the result

`[(b^(3))/(a^(4))]^(-3)`

d)
`[(a^(4))/(b^(3))]^(3)`

e) Simplify

`((a^(4))^(3))/((b^(3))3)`

f) Result

`(a^(12))/(b^(9))`
