Simplify $\sqrt{z^{15}}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $15$ and $n$ equals $\frac{1}{12}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=12$, $c=15$, $a/b=\frac{1}{12}$ e $ca/b=15\cdot \left(\frac{1}{12}\right)$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=15$, $b=12$ e $a/b=\frac{15}{12}$
