Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=4x^6$, $b=5$, $c=1$, $a/b=\frac{4x^6}{5}$, $f=12x^3$, $c/f=\frac{1}{12x^3}$ e $a/bc/f=\frac{4x^6}{5}\frac{1}{12x^3}$

Applicare la formula: $ab$$=ab$, dove $ab=5\cdot 12x^3$, $a=5$ e $b=12$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=4x^6$, $a=4$, $b=x^6$, $c=60$ e $ab/c=\frac{4x^6}{60x^3}$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^3$, $a^m=x^6$, $a=x$, $a^m/a^n=\frac{4x^6}{60x^3}$, $m=6$ e $n=3$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=4x^{3}$, $a=4$, $b=x^{3}$, $c=60$ e $ab/c=\frac{4x^{3}}{60}$
