Simplify $\sqrt[7]{7^{14}}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $14$ and $n$ equals $\frac{1}{7}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=7$, $c=14$, $a/b=\frac{1}{7}$ e $ca/b=14\cdot \left(\frac{1}{7}\right)$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=14$, $b=7$ e $a/b=\frac{14}{7}$

Applicare la formula: $a^b$$=a^b$, dove $a=7$, $b=2$ e $a^b=7^{2}$
