Question

Preciso do cálculo urgente

Answer 1

Resposta:

${7}^{2} = 49$

$7 \times 7 = 49$

${8}^{1} = 8$

${( - 5)}^{3} = - 125$

${( - 10)}^{0} = 1$

$( \frac{3}{4})^{2} = \frac{9}{16}$

$( -\frac{5}{9})^{2} = \frac{25}{81}$

$( {2})^{ - 2} =\frac{1}{4}$

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