Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{9f^7g^5}{3f^3g}$, $a^n=g^5$, $a=g$ e $n=5$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=f^3$, $a^m=f^7$, $a=f$, $a^m/a^n=\frac{9f^7g^{4}}{3f^3}$, $m=7$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=9f^{4}g^{4}$, $a=9$, $b=f^{4}g^{4}$, $c=3$ e $ab/c=\frac{9f^{4}g^{4}}{3}$
