Answer 2

Step-by-step explanation:

$(\frac{81}{16})^{ \frac{ - 3}{4} } + (\frac{25}{9} )^{ \frac{ - 3}{2} } \\ = (\frac{3}{2})^{ 4 \times \frac { - 3}{4} } + (\frac{5}{3} )^{ 2 \times \frac{ - 3}{2} } \\ = (\frac{3}{2})^{ - 3 } + (\frac{5}{3} )^{ - 3 } \\ = (\frac{2}{3})^{ 3 } + (\frac{3}{5} )^{ 3 } \\ = \frac{8}{27} + \frac{27}{125} \\ = \frac{8(125) + 27(27)}{3,375} \\ = \frac{1,000 +729}{3,375} \\ = \frac{1,729}{3,375}$
