Applicare la formula: $\frac{a}{b}=c$$\to a=cb$, dove $a=x^3$, $b=4$ e $c=54$

Applicare la formula: $ab$$=ab$, dove $ab=54\cdot 4$, $a=54$ e $b=4$

Applicare la formula: $x^a=b$$\to \left(x^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}$, dove $a=3$, $b=216$, $x^a=b=x^3=216$ e $x^a=x^3$

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

Applicare la formula: $a^b$$=a^b$, dove $a=216$, $b=\frac{1}{3}$ e $a^b=\sqrt[3]{216}$
