Explanation:

Step1: Recall exponent - root relationship

The fourth - root of a number $z$ can be written as $z^{\frac{1}{4}}$, i.e., $\sqrt[4]{z}=z^{\frac{1}{4}}$.

Step2: Compare with given expression

The given expression is $\sqrt[4]{z}=z^{- 4}$. Since $z^{\frac{1}{4}}
eq z^{-4}$ for $z > 0$ (because the exponents $\frac{1}{4}$ and $-4$ are not equal).

Answer:

False
