Question

Rewrite the expression in z to the n power. The expression I was given is: 1 over z to the negative 1 half power.

Answer 1

Answer:

The equivalent expression is;

$\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}$

Step-by-step explanation:

The given expression is:

$\frac{1}{z^{-\frac{1}{2} }}$

Recall that:

$\frac{1}{a^{-m}}=a^m$

In our case, $a=z$ and  $m=\frac{1}{2}$.

We use this property of exponent to obtain;

$\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}$
