Applicare la formula: $x^a=b$$\to \left(x^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}$, dove $a=\frac{1}{3}$, $b=2$, $x^a=b=\sqrt[3]{x+5}=2$, $x=x+5$ e $x^a=\sqrt[3]{x+5}$

Applicare la formula: $\left(x^a\right)^b$$=x$, dove $a=\frac{1}{3}$, $b=3$, $x^a^b=\left(\sqrt[3]{x+5}\right)^3$, $x=x+5$ e $x^a=\sqrt[3]{x+5}$

Applicare la formula: $a^b$$=a^b$, dove $a=2$, $b=3$ e $a^b=2^3$

Applicare la formula: $x+a=b$$\to x=b-a$, dove $a=5$, $b=8$, $x+a=b=x+5=8$ e $x+a=x+5$

Applicare la formula: $a+b$$=a+b$, dove $a=8$, $b=-5$ e $a+b=8-5$
