[tex] (\frac{16}{81} ) ^{ - \frac{3}{4} } \\ = ( \frac{81}{16} ) ^{ \frac{3}{4} } \\ = ( \frac{3 ^{4} }{2 ^{4} } ) ^{ \frac{3}{4} } \\ = (\frac{3 }{2} ) ^{3} \\ = \frac{27}{8} \\ = 3 \frac{3}{8} [/tex]

[tex] \frac{2 ^{ - 2} \times 3^{4} }{6 ^{3} } \\ = \frac{( \frac{1}{2}) ^{2} \times 81 }{216} \\ = \frac{ \frac{1}{4} \times 81 }{216} \\ = \frac{ \frac{81}{4} }{216} \\ = \frac{81}{4} \div 216 \\ = \frac{81}{4} \times \frac{1}{216} \\ = \frac{(81 \div 27)}{4} \times \frac{1}{(216 \div 27)} \\ = \frac{3}{4} \times \frac{1}{8} \\ = \frac{3}{32} [/tex]
