Answer 1

The expression that applies the power rule properly to simplify this expression is (7^-8)^-4 = 7^32

How to determine the expression that applies the power rule properly to simplify this expression?

The power rule states that:

(x^a)^b = x^ab

This means that we expand the bracket by multiplying the power

Using the above as an illustration, we have:

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

Hence, the expression that applies the power rule properly to simplify this expression is (7^-8)^-4 = 7^32
