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

Applicare la formula: $a^b$$=a^b$, dove $a=2$, $b=3$ e $a^b=2^3$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=8$, $c=-8$, $a/b=\frac{1}{8}$ e $ca/b=-8\cdot \left(\frac{1}{8}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=-8\cdot 1$, $a=-8$ e $b=1$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=-8$, $b=8$ e $a/b=-\frac{8}{8}$
