Answer 1

Oie, tudo bom?

$= 5 \: . \: 3(2 - 7) {}^{3} \div 8 + 172 \\ = 5 \: . \: 3 \: . \: ( - 5) {}^{3} \div 8 + 172 \\ = 5 \: .\: 3 \: . \: ( - 5 {}^{3} ) \div 8 + 172 \\ = - 5 \: . \: 3 \: . \: 5 {}^{3} \div 8 + 172 \\ = - \frac{5 \: . \: 3 \: . \: 5 {}^{3} }{8} + 172 \\ = - \frac{5 \: . \: 3 \: . \: 125 }{8} + 172\\ = - \frac{1875}{8} + 172 \\ = \frac{ - 1875 + 1376}{8} \\ = \frac{ - 499}{8} \\ = - \frac{499}{8} \\ \boxed{ = - 62,375}$
