Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{-15x^6y^6}{-3x^3y}$, $a^n=y^6$, $a=y$ e $n=6$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^3$, $a^m=x^6$, $a=x$, $a^m/a^n=\frac{-15x^6y^{5}}{-3x^3}$, $m=6$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=-15x^{3}y^{5}$, $a=-15$, $b=x^{3}y^{5}$, $c=-3$ e $ab/c=\frac{-15x^{3}y^{5}}{-3}$
