Applicare la formula: $\left(ab\right)^n$$=a^nb^n$

Applicare la formula: $a^b$$=a^b$, dove $a=16$, $b=2$ e $a^b=16^2$

Applicare la formula: $\left(x^a\right)^b$$=x^{ab}$, dove $a=\frac{2}{3}$, $b=2$, $x^a^b=\left(\sqrt[3]{u^{2}}\right)^2$, $x=u$ e $x^a=\sqrt[3]{u^{2}}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=2$, $b=3$, $c=2$, $a/b=\frac{2}{3}$ e $ca/b=2\left(\frac{2}{3}\right)$

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