If $n$ and $k$ are both numbers then \[k^{n} = \left( \frac{1}{k}\right)^{n}.\] For example \[6^{2} = \left(\frac{1}{6}\right)^2 = \frac{1^2}{6^2} = \frac{1}{36}.\] In your example \[\left(\frac{2}{3}\right)^{6} = \left(\frac{1}{\frac{2}{3}}\right)^{6}.\] Can you simplify this expression? Write back if you need more assistance,
