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

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=3$, $b=8$, $c=1$, $a/b=\frac{3}{8}$, $f=x^{\left|-\frac{3}{13}\right|}$, $c/f=\frac{1}{x^{\left|-\frac{3}{13}\right|}}$ e $a/bc/f=\frac{3}{8}\frac{1}{x^{\left|-\frac{3}{13}\right|}}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=3$, $b=8$, $c=1$, $a/b=\frac{3}{8}$, $f=\sqrt[13]{x^{3}}$, $c/f=\frac{1}{\sqrt[13]{x^{3}}}$ e $a/bc/f=\frac{3}{8}\frac{1}{\sqrt[13]{x^{3}}}$
