    A. (-16)^¼ :

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

    It’s stuck at here

    So, the choice A is False

    B. (-4)^½ :

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

    Stuck at here too

    So, the choice B is False

    C. (-32)^1/5 :

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

    The result is -2. It’s real number

    So, the choice C is True ✔️

    D. (-8)^⅓ :

     {( - 8)}^{ \frac{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 :)
