Answer 1

Ответ:

2)

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

4)

${( \frac{2}{5}) }^{3} = \frac{ {2}^{3} }{ {5}^{3} } = \frac{8}{125} = 0.064$

6)

${(1.25)}^{ - 2} = \frac{1}{ {1.25}^{2} } = \frac{1}{1.5625} = 0.64$

8)

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

10)

${( - 2.25)}^{ - 1} = - \frac{1}{2.25} = - \frac{100}{225}$

12)

$-( { - 2 \times \frac{1}{3}) }^{ - 2} = - ( - { \frac{7}{3} )}^{ - 2} = \\ - ( - { \frac{3}{7}) }^{2} = - \frac{9}{49}$
