Question

Помогите пожалуйста срочно

Answer 1

$( \frac{1}{2} ) {}^{2} = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} = 4 {}^{ - 1} \\ ( \frac{ - 1}{2} ) {}^{5} = \frac{ - 1}{2} \times (\frac{ - 1}{2}) \times ( \frac{ - 1}{2} )\times (\frac{ - 1}{2} ) \times ( \frac{ - 1}{2} ) = - \frac{1}{32} = - 2 {}^{ - 5} \\ ( - \frac{2}{3}) {}^{2} = - \frac{2}{3} \times ( - \frac{2}{3} ) = \frac{4}{9} = ( \frac{2}{3} ) {}^{2} \\ 0.3 {}^{3} = (\frac{3}{10} ) {}^{3} = \frac{3}{10} \times \frac{3}{10} \times \frac{3}{10} = \frac{27}{1000} = 0.027$
