Answer 2

Answer:

${2}^{ - 3} +( 0.01)^{ - \frac{1}{2} } - ( {27})^{ \frac{2}{3} } \\ \\ \\ = \frac{1}{ {2}^{3} } + \frac{1}{100 ^{ \frac{1}{2} } } - ((3) ^{3} )^{ \frac{2}{3} } \\ \\ \\ = \frac{1}{8} + \frac{1}{ \sqrt{100} } - {3}^{3 \times \frac{2}{3} } \\ \\ \\ = \frac{1}{8} + \frac{1}{10} - 9 \\ \\ \\ \frac{5 + 4 - 360}{40} \\ \\ \\ = \frac{ - 351}{40}$
