CheckWhich applies the power of a power rule properly to simplify this expression?(7-8)O (78)4 = 7-8) +(-4) = 7-12 =17121O (7-8)4 = 7(+8)+(-4) = 74 =741O (7-3) = 71-8)(-4) = 7-32 =732O 7-8,4 = 7(-8)(-4) = 72IntroDone

Answer 1

We are given the expression below

$(7^{-8})^{-4}$

This expression can be solved by using one of the laws of indices which is denoted below:

$(a^m)^n=a^{m\times n}$

Using the above the given expression beocmes
