Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=4^{\left(3n+2\right)}$, $a^m=4^{\left(n+1\right)}$, $a=4$, $a^m/a^n=\frac{2^n4^{\left(n+1\right)}8^{\left(n+2\right)}}{4^{\left(3n+2\right)}}$, $m=n+1$ e $n=3n+2$

Applicare la formula: $-\left(a+b\right)$$=-a-b$, dove $a=3n$, $b=2$, $-1.0=-1$ e $a+b=3n+2$

Applicare la formula: $a+b$$=a+b$, dove $a=1$, $b=-2$ e $a+b=n+1-3n-2$
