Question

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

(7^8)^-4

Answer 1

For this case we have that by definition of power properties is met:

$(a^m)^n=a^{m*n}$

It is also true that:

$a^{-1}=\frac{1}{a^1}=\frac{1}{a}$

So, rewriting the expression we have:

$7^{-32}=\frac{1}{7^{32}}$

Answer:

$(a^m)^n=a^{m*n}$

$a^{-1}=\frac{1}{a^1}=\frac{1}{a}$

Answer 2

Answer:(7^-8)^-4=7^(-8)(-4)=7^32
