Question

Which expression is equivalent to 5−4 / 4^−3 I'm trying not to fail this so that's why i threw this up here.

A. -64

B. -1/64

C. 1/64

D. 64

Answer 1

D. 64

Explanation:

5−4 / 4^−3

5-4 = 1

4^-3

The negative in the exponent means to flip it

4^-3 = 1/4^3 = 1/64

5−4 / 4^−3 = 1 / (1/64) = 64
