Applicare la formula: $\frac{a}{a}$$=1$, dove $a=125$ e $a/a=\frac{125x^8y^2}{125x^3y}$

Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{x^8y^2}{x^3y}$, $a^n=y^2$, $a=y$ e $n=2$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^3$, $a^m=x^8$, $a=x$, $a^m/a^n=\frac{x^8y}{x^3}$, $m=8$ e $n=3$
