Question

Simplify (-2)^-3
a. -8
b. -1/8
c. 1/8
d. 8

Answer 1

B.) -1/8

Explanation:

You flip the problem because of the negative exponent

`(1)/(-2^3)`

This makes the exponent positive

Expand the denominator

(-2) * (-2) * (-2) = 4*(-2) = -8

1/-8 = -1/8

Answer 2

Its D because 2×2×2 equals 8 and they are both minus and knowing - times - makes + so it becomes 8
