Answer 1

Resposta:

$( \frac{7}{2} {)}^{2} - ( \frac{3}{2} {)}^{2} - 15 \times \frac{2}{3} + (2 - \frac{1}{8} ) \\ \\( \frac{7}{2} {)}^{2} - ( \frac{3}{2} {)}^{2} - 15 \times \frac{2}{3} + \frac{15}{8} \\ \\ \frac{49}{4} - \frac{9}{4} - 5 \times 2 + \frac{15}{8} \\ \\ \frac{49}{4} - \frac{9}{4} - 10 + \frac{15}{8} \\ \\ \frac{15}{8} = 1,875$
