2^-4=-2 x -2 x -2 x -2 = -16

A. Taylor changed the negative exponent to a negative base. The problem should be 2^-4=1/2^4=1/2x2x2x2=1/16****
B. Taylor did not multiply correctly. The answer should be 16.
C. Taylor made the answer positive. The answer should be -16
D. Taylor did not multiply by -1. The problem should be 2^-4=(-1)1/2^4=(-1)1/2x2x2x2=1/16

I think the answer is A. Taylor changed the negative exponent to a negative base. The problem should be 2^-4=1/2^4=1/2x2x2x2=1/16****

you are correct
