Applicare la formula: $\frac{a^n}{a}$$=a^{\left(n-1\right)}$, dove $a^n/a=\frac{270x^{10}}{5x}$, $a^n=x^{10}$, $a=x$ e $n=10$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=270x^{9}$, $a=270$, $b=x^{9}$, $c=5$ e $ab/c=\frac{270x^{9}}{5}$

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

Applicare la formula: $\left(x^a\right)^b$$=x^{ab}$, dove $a=9$, $b=\frac{1}{2}$, $x^a^b=\sqrt{x^{9}}$ e $x^a=x^{9}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=9$, $a/b=\frac{1}{2}$ e $ca/b=9\cdot \left(\frac{1}{2}\right)$
