Question

Which applies the power of a power rule properly to simplify this expression?

Answer 1

7^32, the fourth option

Explanation:

For the power rule, if you have a number to a power, for example
`x^(a)` and raise it to another power so it becomes,
`(x^(a) )^(b)`, We simplify by multiplying the powers together. So the simplified answer would be
`x^((a*b))`.

Answer 2

D.

Explanation:

[7^(-8)]^(-4) =

A power raised to a power: multiply the exponents.

= 7^[(-8)*(4)]

= 7^(32)

Answer: D.
