A. (-16)^¼ :


( - 16) { }^{ (1)/(4) } = \sqrt[4]{( - 16)}

It's stuck at here

So, the choice A is False

B. (-4)^½ :


{( - 4)}^{ (1)/(2) } = \sqrt[2]{( - 4)}

Stuck at here too

So, the choice B is False

C. (-32)^1/5 :


{( - 32)}^{ (1)/(5) } = \sqrt[5]{( - 32)} = - 2

The result is -2. It's real number

So, the choice C is True ✔️

D. (-8)^⅓ :


{( - 8)}^{ (1)/(3) } = \sqrt[3]{( - 8)} = - 2

The result is -2. It's real number too

So, the choice D is True ✔️

So, the choices are real numbers is C and D

Hope it helpful and useful :)
