Simplify $\sqrt{\left(x^{-4}\right)^{3}}\right)^2}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $2$ and $n$ equals $\frac{1}{6}$

Simplify $\sqrt{\left(x^{-4}\right)^{3}}}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $\frac{3}{4}$ and $n$ equals $\frac{1}{3}$

Simplify $\left(x^{-4}\right)^{\frac{3}{4}\cdot \frac{1}{3}}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $-4$ and $n$ equals $\frac{3}{4}\cdot \frac{1}{3}$

Applicare la formula: $x^a$$=\frac{1}{x^{\left|a\right|}}$, dove $a=-1$
