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

Applicare la formula: $x^mx^n$$=x^{\left(m+n\right)}$, dove $m=\frac{1}{3}-\sqrt[3]{y}$ e $n=\frac{1}{3}$

Applicare la formula: $\frac{a}{b}+\frac{c}{b}$$=\frac{a+c}{b}$, dove $a=1$, $b=3$ e $c=1$

Applicare la formula: $a+b$$=a+b$, dove $a=1$, $b=1$ e $a+b=1+1$
