Answer:

The answer is the second one: [tex](-1/2)^{-3}[/tex]

Step-by-step explanation:

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

[tex](-1/2)^{-3}[/tex] = [tex](-2/1)^3[/tex]= [tex]-2^3[/tex]

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

[tex]-2^3[/tex] = -8

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

I hope this help, firend!!
