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

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

Applicare la formula: $\left(x^a\right)^b$$=x^{ab}$, dove $a=\frac{1}{2}$, $b=4$, $x^a^b=\left(\sqrt{x^2+y^2}\right)^4$, $x=x^2+y^2$ e $x^a=\sqrt{x^2+y^2}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=4$, $a/b=\frac{1}{2}$ e $ca/b=4\left(\frac{1}{2}\right)$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=4$, $b=2$ e $a/b=\frac{4}{2}$
