Applicare la formula: $\frac{a}{a}$$=1$, dove $a=c^3$ e $a/a=\frac{18a^4b^5c^3}{3a^2bc^3}$

Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{18a^4b^5}{3a^2b}$, $a^n=b^5$, $a=b$ e $n=5$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=a^2$, $a^m=a^4$, $a^m/a^n=\frac{18a^4b^{4}}{3a^2}$, $m=4$ e $n=2$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=18a^{2}b^{4}$, $a=18$, $b=a^{2}b^{4}$, $c=3$ e $ab/c=\frac{18a^{2}b^{4}}{3}$
