Simplify $\sqrt{x^{49}}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $49$ and $n$ equals $\frac{1}{10}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=10$, $c=49$, $a/b=\frac{1}{10}$ e $ca/b=49\cdot \left(\frac{1}{10}\right)$
