Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}$, dove $a=8$ e $b=\sqrt{8}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=8$, $b=\sqrt{8}$, $c=\sqrt{8}$, $a/b=\frac{8}{\sqrt{8}}$, $f=\sqrt{8}$, $c/f=\frac{\sqrt{8}}{\sqrt{8}}$ e $a/bc/f=\frac{8}{\sqrt{8}}\cdot \frac{\sqrt{8}}{\sqrt{8}}$

Applicare la formula: $\frac{a}{a}$$=1$, dove $a=8$ e $a/a=\frac{8\sqrt{8}}{8}$
