Answer 2

Step-by-step explanation:

${81}^{ \frac{ - 3}{4} } = { {3}^{4} }^{ \frac{ - 3}{4} } = {3}^{ \frac{ - 3 \times 4}{4} } = {3}^{ - 3} = \frac{1}{ {3}^{3} } = \frac{1}{27}$

$5 \times {16}^{ \frac{3}{4} } = 5 \times { {(2}^{4} )}^{ \frac{3}{4} } = 5 \times {2}^{ \frac{3 \times 4}{4} } \\ = 5 \times {2}^{3} = 5 \times 8 = 40$

$(0.000064)^{ \frac{5}{6} } = {(64 \times 10^{ - 6}) }^{ \frac{5}{6} } \\ = {(64)}^{ \frac{5}{6} } \times {(10^{ - 6} )}^{ \frac{5}{6} } \\ { ({2}^{6} )}^{ \frac{5}{6} } \times {10}^{ \frac{ - 6 \times 5}{6} } \\ {2}^{5} \times {10}^{ - 5} = { \frac{2}{10} }^{5} = 0.2 ^{5}$
