Applicare la formula: $x^a=b$$\to \left(x^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}$, dove $a=\frac{1}{4}$, $b=3$, $x^a=b=\sqrt[4]{x}=3$ e $x^a=\sqrt[4]{x}$

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

Applicare la formula: $a^b$$=a^b$, dove $a=3$, $b=4$ e $a^b=3^4$
