2) \(\left( \frac{1}{8} \right)^{6} = \left( \frac{1}{4} \right)^{3}\)
3) \(\left( \frac{1}{16} \right)^{2} = \left( \frac{1}{8} \right)^{3}\)
4) \(\left( \frac{1}{16} \right)^{3} = \left( \frac{1}{8} \right)^{7}\)
5) \(\left( \frac{1}{16} \right)^{3} = \left( \frac{1}{2} \right)^{6}\)
6) \(\left( \frac{1}{32} \right)^{4} = \left( \frac{1}{8} \right)^{3}\)
7) \(\left( \frac{1}{9} \right)^{2} = \left( \frac{1}{27} \right)^{1}\)
8) \(\left( \frac{1}{9} \right)^{2} = \left( \frac{1}{27} \right)^{3}\)
