Question

Simplify. (-2)-3
A) -8
B)-1/8
C)1/8
D)8

Answer 1

B. -1/8.

Explanation:

I guess you mean (-2)^-3

= 1 / (-2)^3

= 1 / -8

= -1/8.

Answer 2

B if you mean (-2)^(-3)

Explanation:

(-2)-3=-5

But based on the answers I think you meant to write (-2)^(-3)

which means 1/(-2)^3

So we have 1/(-2*-2*-2)=1/-8 or -1/8
