Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{36x^4y^3}{4x^3y}$, $a^n=y^3$, $a=y$ e $n=3$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^3$, $a^m=x^4$, $a=x$, $a^m/a^n=\frac{36x^4y^{2}}{4x^3}$, $m=4$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=36xy^{2}$, $a=36$, $b=xy^{2}$, $c=4$ e $ab/c=\frac{36xy^{2}}{4}$
