Answer:


(-7)^-^4=(1)/((-7)^4)

Explanation:

The user aswati already wrote the correct answer, but I wanted to help explain why their answer is correct so that you'll understand.

According to the negative exponent rule, when a base (let's call it m) is raised to a negative exponent (let's call it n), we rewrite it as a fraction where the numerator is 1 and the denominator is the base raised to the same exponent turned positive.

Thus, the negative exponent rule is given as:


b^-^n=(1)/(b^n)

Thus,
(-7)^-^4 becomes
(1)/((-7)^4)
