Question

O valor da expressão 1-(13/3 - 11/3) +3 x (4/3)²+2÷3/5 é?.

Answer 1

Resposta:

resulta em 9

Explicação passo a passo:

$1-(\frac{13}{3}-\frac{11}{3})+3.(\frac{4}{3})^2+2/(\frac{3}{5})$ =

$1-(\frac{13-11}{3})+3.(\frac{16}{9})+2.\frac{5}{3}=$

$1-(\frac{2}{3})+\frac{16}{3}+\frac{10}{3}=$

$\frac{3-2}{3}+\frac{16}{3}+\frac{10}{3}=\\ \\\frac{1}{3}+\frac{16}{3}+\frac{10}{3}=\\ \\ \frac{1+16+10}{3}=\\ \\\frac{27}{3}=\\ \\9$
