Simplify $\left(a^4\right)^2$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $4$ and $n$ equals $2$

Applicare la formula: $ab$$=ab$, dove $ab=4\cdot 2$, $a=4$ e $b=2$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=a^5$, $a^m=a^{8}$, $a^m/a^n=\frac{a^{8}}{a^5}$, $m=8$ e $n=5$
