Applicare la formula: $\frac{a}{a}$$=1$, dove $a=y^3$ e $a/a=\frac{12w^9y^3}{-3w^3y^3}$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=w^3$, $a^m=w^9$, $a=w$, $a^m/a^n=\frac{12w^9}{-3w^3}$, $m=9$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=12w^{6}$, $a=12$, $b=w^{6}$, $c=-3$ e $ab/c=\frac{12w^{6}}{-3}$
