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

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

Applicare la formula: $\left(\frac{a}{b}\right)^n$$=\left(\frac{b}{a}\right)^{\left|n\right|}$, dove $a=2n$, $b=3m$ e $n=-2$

Applicare la formula: $\left(\frac{a}{b}\right)^n$$=\frac{a^n}{b^n}$, dove $a=3m$, $b=2n$ e $n=2$
