Answer 1

Объяснение:

1).

${2}^{ - 3} = \frac{1}{ {2}^{3} } = \frac{1}{8}$

2).

${( - 3)}^{ -3} = \frac{1}{( - 3)^{3} } = - \frac{1}{27}$

3).

${( - 1)}^{ - 22} = \frac{1}{( - 1)^{22} } = \frac{1}{1} = 1$

4).

$( \frac{2}{5})^{3} = \frac{8}{125}$

5).

$0.02 ^{ - 3} = \frac{1}{0.02^{3} } = \frac{1}{( \frac{1}{50})^{3} } = \frac{1}{ \frac{1}{125000} } = 125000$

6).

${1.25}^{ - 2} = \frac{1}{ {1.25}^{2} } = \frac{1}{( \frac{5}{4})^{2} } = \frac{1}{ \frac{25}{16} } = \frac{16}{25}$

7).

$- 4 ^{ - 3} = \frac{1}{ - 4 ^{3} } = \frac{1}{ - 64} = - \frac{1}{64}$

8).

$( - 0.3)^{ - 2} = \frac{1}{( - 0.3)^{2} } = \frac{1}{0.09} = \frac{1}{ \frac{9}{100} } = \frac{100}{9} = 11 \frac{1}{9}$
