Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}$, dove $a=5w$ e $b=3\sqrt{143}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=5w$, $b=3\sqrt{143}$, $c=\sqrt{143}$, $a/b=\frac{5w}{3\sqrt{143}}$, $f=\sqrt{143}$, $c/f=\frac{\sqrt{143}}{\sqrt{143}}$ e $a/bc/f=\frac{\sqrt{143}}{\sqrt{143}}\frac{5w}{3\sqrt{143}}$

Applicare la formula: $ab$$=ab$, dove $ab=3\cdot 143$, $a=3$ e $b=143$
