Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{-6a^2b^3}{-2ab}$, $a^n=a^2$ e $n=2$

Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{-6ab^3}{-2b}$, $a^n=b^3$, $a=b$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=-6ab^{2}$, $a=-6$, $b=ab^{2}$, $c=-2$ e $ab/c=\frac{-6ab^{2}}{-2}$
