Applicare la formula: $\frac{a^n}{b^n}$$=\left(\frac{a}{b}\right)^n$, dove $a^n=12^2$, $a=12$, $b=-2$, $b^n={\left(-2\right)}^2$, $a^n/b^n=\frac{12^2}{{\left(-2\right)}^2}$ e $n=2$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=12$, $b=-2$ e $a/b=\frac{12}{-2}$

Applicare la formula: $a^b$$=a^b$, dove $a=-6$, $b=2$ e $a^b={\left(-6\right)}^2$
