Applicare la formula: $\frac{a}{a}$$=1$, dove $a=b^3$ e $a/a=\frac{8a^6b^3c^7}{4a^3b^3d^4}$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=a^3$, $a^m=a^6$, $a^m/a^n=\frac{8a^6c^7}{4a^3d^4}$, $m=6$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=8a^{3}c^7$, $a=8$, $b=a^{3}c^7$, $c=4$ e $ab/c=\frac{8a^{3}c^7}{4d^4}$
