Answer:
Second choice is the correct one

Step-by-step explanation:
Let's check the choices:
Choice 1:
-2^-3 = -1/(2)^3 = -1/8 ........> wrong choice
Choice 2:
(-1/2)^-3 = (-2)^3 = -8 ......> correct choice
Choice 3:
(1/2)^-3 = (2)^3 = 8 ........> wrong choice
Choice 4:
2^-3 = (1/2)^3 = 1/8 ..........> wrong choice

Hope this helps :)

A number raised to a negative power is equal to 1 divided by the number raised to the same power but positive
therefore
[-1/2]^-3-----------> [-2]^3 =-8

the answer is [-1/2]^-3
