Applicare la formula: $ab$$=ab$, dove $ab=4\cdot 2a\left(a^2\right)^2$, $a=4$ e $b=2$

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

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

Applicare la formula: $x\cdot x^n$$=x^{\left(n+1\right)}$, dove $x^nx=8a\cdot a^{4}$, $x=a$, $x^n=a^{4}$ e $n=4$

Applicare la formula: $a+b$$=a+b$, dove $a=4$, $b=1$ e $a+b=4+1$
