Answer:

Option "B" is the correct answer to the following question.

Step-by-step explanation:

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

-2\times -2\times -2

[tex](\frac{1}{a} )^{-m}= a^m[/tex]

So,

[tex](\frac{-1}{2} )^{-3} = (-2)^3\\\\(-2)^3 = -2\times -2\times -2\\\\ -2\times -2\times -2=-8[/tex]

Therefore, Option "B" is the correct answer
