Applicare la formula: $x^a$$=\frac{1}{x^{\left|a\right|}}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=4$, $b=3$, $c=1$, $a/b=\frac{4}{3}$, $f=x^{\left|-\frac{2}{3}\right|}$, $c/f=\frac{1}{x^{\left|-\frac{2}{3}\right|}}$ e $a/bc/f=\frac{4}{3}\frac{1}{x^{\left|-\frac{2}{3}\right|}}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=4$, $b=3$, $c=1$, $a/b=\frac{4}{3}$, $f=\sqrt[3]{x^{2}}$, $c/f=\frac{1}{\sqrt[3]{x^{2}}}$ e $a/bc/f=\frac{4}{3}\frac{1}{\sqrt[3]{x^{2}}}$
