Question

Which expression is equivalent to -8?

Answer 1

2^-3

Explanation:

Answer 2

The answer is the second one:
`(-1/2)^(-3)`

Explanation:

1) When an exponent is negative, we must 'flip' the term before applying the exponent.

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

2) Next, we need to cube two. Remember, the negative number does not apply yet!

`-2^3` = -8

3) Thus, we get our answer. -8.
