Answer 1

Resposta:

$a)0 {}^{7 = }0 \\ b) - 5 {}^{2} = - 5 \times 5 = - 25 \\ c) - (1.2) {}^{2} = - (1.2) \times (1.2) = - 1.44 \\ d)( - 5) {}^{2} = ( - 5) \times ( - 5) = - 25 \\ e) - (0.3) {}^{0 } = - 1 \\ f)( \frac{ - 2}{3} ) {}^{3} = ( \frac{ - 2}{3} )( \frac{ - 2}{3})( \frac{ - 2}{3}) = - \frac{8}{27} \\ g) - ( \frac{2}{5} ) {}^{3} = - \frac{2}{5} \frac{2}{5} \frac{2}{5} = \frac{ - 8}{125}$
