Explicação passo-a-passo:

$a)( \frac{3}{2} ) {}^{ - 1} = \frac{2}{3}$

$b)( \frac{2}{5} ) {}^{ - 1} = \frac{5}{2}$

$c)0.3 {}^{ - 1} = ( \frac{3}{10} ) {}^{1} = \frac{3}{10}$

$d)0.5 {}^{ - 1} = ( \frac{5}{10} ) {}^{1} = \frac{5}{10} = \frac{1}{2}$

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

$f)( \frac{2}{3} ) {}^{ - 1} = ( \frac{3}{2} ) {}^{1} = \frac{3}{2}$
