Simplify $\left(x^2\right)^{-3}$ 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 $-3$

Wenden Sie die Formel an: $x^a$$=\frac{1}{x^{\left|a\right|}}$

Wenden Sie die Formel an: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, wobei $a=9$, $b=x^{6}$, $c=1$, $a/b=\frac{9}{x^{6}}$, $f=z$, $c/f=\frac{1}{z}$ und $a/bc/f=\frac{9}{x^{6}}y^3\frac{1}{z}$
