Simplify $\sqrt{3^8}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $8$ and $n$ equals $\frac{1}{2}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=8$, $a/b=\frac{1}{2}$ e $ca/b=8\cdot \left(\frac{1}{2}\right)$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=8$, $b=2$ e $a/b=\frac{8}{2}$

Applicare la formula: $a^b$$=a^b$, dove $a=3$, $b=4$ e $a^b=3^{4}$
