1.
[tex] {3}^{ - 3} \times { (\frac{2}{3}) }^{ - 2} \\ = \frac{1}{ {3}^{3} } \times \frac{ {3}^{2} }{ {2}^{2} } \\ = \frac{1}{12} [/tex]
2.
[tex] \frac{1}{ {( \frac{2}{5}) }^{7} } \\ = \frac{1}{ \frac{ {2}^{7} }{ {5}^{7} } } \\ = \frac{ {5}^{7} }{ {2}^{7} } [/tex]
3.
[tex] \frac{1}{ {( \frac{ - 6}{5} )}^{3} } \\ = \frac{1}{ \frac{ {( - 6)}^{3} }{ {5}^{3} } } \\ = \frac{ {5}^{3} }{ {( - 6)}^{3} } [/tex]
4.
[tex] \frac{m. {n}^{6} }{ {( {m}^{2}) }^{3} } \\ = \frac{m. {n}^{6} }{ {m}^{6} } \\ = \frac{ {n}^{6} }{ {m}^{5} } [/tex]
