Answer 1

Step-by-step explanation:

${2}^{ - 3} + {0.01}^{ \frac{ - 1}{2} } - {27}^{ \frac{2}{3} } \\ \frac{1}{ {2}^{3} } + ({.1}^{2} ) ^{ \frac{ - 1}{2} } - (3 ^{3} ) ^{ \frac{2}{3} } \\ \frac{1}{8} + (0.1)^{ 2 \times \frac{ - 1}{2} } - (3) ^{3 \times \frac{2}{3} } \\ \frac{1}{8} + \frac{1}{0.1} - 3^{2} \\ = \frac{1}{8} + 10 - 9 = \frac{1}{8} + 1 \\ = \frac{1 + 8}{8} = \frac{9}{8} = 1 \frac{1}{8}$

hope it helps...
