Applicare la formula: $x^a=b$$\to \left(x^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}$, dove $a=3$, $b=27$, $x^a=b=\left(x+2\right)^3=27$, $x=x+2$ e $x^a=\left(x+2\right)^3$

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

Applicare la formula: $a^b$$=a^b$, dove $a=27$, $b=\frac{1}{3}$ e $a^b=\sqrt[3]{27}$

Applicare la formula: $x+a=b$$\to x=b-a$, dove $a=2$, $b=3$, $x+a=b=x+2=3$ e $x+a=x+2$

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