Which expression is equivalent to 4^-5?

A. (4) (4) (4) (4) (4)

B. 1 / (4) (4) (4) (4) (4)

C. (-4) (-4) (-4) (-4) (-4)

D. - 1 / (4) (4) (4) (4) (4)

Since there is a negative exponent, you need to first convert that into a positive exponent which is going to be 1/4^5

Then, we can find out the answer by simply breaking apart the exponents into 5 groups of 4.

1 / (4) (4) (4) (4) (4)

Answer: B
