Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{3x^5y^3}{15x^3y}$, $a^n=y^3$, $a=y$ e $n=3$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^3$, $a^m=x^5$, $a=x$, $a^m/a^n=\frac{3x^5y^{2}}{15x^3}$, $m=5$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=3x^{2}y^{2}$, $a=3$, $b=x^{2}y^{2}$, $c=15$ e $ab/c=\frac{3x^{2}y^{2}}{15}$
