Applicare la formula: $\left(ab\right)^n$$=a^nb^n$

Applicare la formula: $\left(x^a\right)^b$$=x^{ab}$, dove $a=3$, $b=4$, $x^a^b=\left(x^3\right)^4$ e $x^a=x^3$

Applicare la formula: $ab$$=ab$, dove $ab=3\cdot 4$, $a=3$ e $b=4$

Applicare la formula: $ab$$=ab$, dove $ab=3\cdot 4$, $a=3$ e $b=4$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^4$, $a^m=x^{12}$, $a=x$, $a^m/a^n=\frac{x^{12}\left(-2y^3\right)^4}{-3yx^4}$, $m=12$ e $n=4$
