Applicare la formula: $\frac{x^a}{b}$$=\frac{1}{bx^{-a}}$, dove $a=-12$ e $b=\frac{1}{4}y^{-6}$

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

Applicare la formula: $\frac{a}{\frac{b}{c}}$$=\frac{ac}{b}$, dove $a=1$, $b=1$, $c=4$, $a/b/c=\frac{1}{\frac{1}{4}\frac{1}{y^{6}}x^{12}}$ e $b/c=\frac{1}{4}$

Applicare la formula: $\frac{a}{\frac{b}{c}}$$=\frac{ac}{b}$, dove $a=4$, $b=1$, $c=y^{6}$, $a/b/c=\frac{4}{\frac{1}{y^{6}}x^{12}}$ e $b/c=\frac{1}{y^{6}}$
