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

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

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

Applicare la formula: $ab$$=ab$, dove $ab=- 1\sqrt[3]{+1}$, $a=-1$ e $b=1$

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