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

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=3$, $b=\sqrt{2}a$, $c=\sqrt{2}$, $a/b=\frac{3}{\sqrt{2}a}$, $f=\sqrt{2}$, $c/f=\frac{\sqrt{2}}{\sqrt{2}}$ e $a/bc/f=\frac{\sqrt{2}}{\sqrt{2}}\frac{3}{\sqrt{2}a}$

Applicare la formula: $x\cdot x$$=x^2$, dove $x=\sqrt{2}$

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