Applicare la formula: $\left(ab\right)^n$$=a^nb^n$

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

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=1$, $b=a^{8}$, $c=1$, $a/b=\frac{1}{a^{8}}$, $f=b^{20}$, $c/f=\frac{1}{b^{20}}$ e $a/bc/f=\frac{1}{a^{8}}\frac{1}{b^{20}}\frac{1}{c^{12}}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=1$, $b=a^{8}b^{20}$, $c=1$, $a/b=\frac{1}{a^{8}b^{20}}$, $f=c^{12}$, $c/f=\frac{1}{c^{12}}$ e $a/bc/f=\frac{1}{a^{8}b^{20}}\frac{1}{c^{12}}$
