Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=x^{-3}$, $a^m=x^{10}$, $a=x$, $a^m/a^n=\frac{x^{10}}{x^{-3}}$, $m=10$ e $n=-3$

Applicare la formula: $x^mx^n$$=x^{\left(m+n\right)}$, dove $m=6$ e $n=13$

Applicare la formula: $a+b$$=a+b$, dove $a=6$, $b=13$ e $a+b=6+13$

Simplify $\left(x^{19}\right)^2$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $19$ and $n$ equals $2$

Applicare la formula: $ab$$=ab$, dove $ab=19\cdot 2$, $a=19$ e $b=2$
