Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^4$, $a^m=x^5$, $a=x$, $a^m/a^n=\frac{6x^5z^3}{4x^4z^2}$, $m=5$ e $n=4$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=z^2$, $a^m=z^3$, $a=z$, $a^m/a^n=\frac{6xz^3}{4z^2}$, $m=3$ e $n=2$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=6xz$, $a=6$, $b=xz$, $c=4$ e $ab/c=\frac{6xz}{4}$
