Answer 2

Answer:

${(64)}^{ \frac{ - 1}{2} } + {(81)}^{ \frac{3}{4} } \\ \\ = > \frac{1}{ {(64)}^{ \frac{1}{2} } } + {(81)}^{ \frac{3}{4} } \\ \\ = > \frac{1}{ ({ {8}^{2} )}^{ \frac{1}{2} } } + { ({3}^{4}) }^{ \frac{3}{4} } \\ \\ = > \frac{1}{ {8}^{2 \times \frac{1}{2} } } + {3}^{4 \times \frac{3}{4} } \\ \\ = > \frac{1}{8} + {3}^{3} = \frac{1}{8} + 27 \\ \\ = > \frac{1 + 216}{8} = \frac{217}{8}$
