Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}$, dove $a=27$ e $b=\sqrt{27}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=27$, $b=\sqrt{27}$, $c=\sqrt{27}$, $a/b=\frac{27}{\sqrt{27}}$, $f=\sqrt{27}$, $c/f=\frac{\sqrt{27}}{\sqrt{27}}$ e $a/bc/f=\frac{27}{\sqrt{27}}\cdot \frac{\sqrt{27}}{\sqrt{27}}$

Applicare la formula: $\frac{a}{a}$$=1$, dove $a=27$ e $a/a=\frac{27\sqrt{27}}{27}$
