Hey friend,
Here is the answer you were looking for:
$( \frac{16}{81} )^{ - \frac{3}{4} } \\ \\ = ( \frac{81}{16} )^{ \frac{3}{4} } \\ \\ = ( \frac{( {3})^{4} }{( {2})^{4} } )^{ \frac{3}{4} } \\ \\ = \frac{( {3})^{4 \times \frac{3}{4} } }{( {2})^{4 \times \frac{3}{4} } } \\ \\ = \frac{( {3})^{3} }{( {2})^{3} } \\ \\ = \frac{27}{8}$

Hope this helps!!!
