Question

quanto é $\frac{2}{5} + (\frac{3}{2} : \frac{1}{4} ) - \sqrt\frac{1}{9}$ me ajuda pfv é pra amanhã!

Answer 1

Resposta:

$\boxed{S=\{\dfrac{91}{15}\}}$

Explicação passo-a-passo:

$\dfrac{2}{5} + (\dfrac{3}{2}:\dfrac{1}{4}) - \sqrt{\dfrac{1}{9}}\\\\\\\dfrac{2}{5} + (\dfrac{3}{2}.\dfrac{4}{1}) - \dfrac{1}{3}\\\\\dfrac{2}{5} + (\dfrac{12}{2}) - \dfrac{1}{3}\\\\\dfrac{2}{5} + \dfrac{6}{1} - \dfrac{1}{3}\\\\\\\dfrac{6+90-5}{15} =\dfrac{91}{15}\\\\\\\boxed{S=\{\dfrac{91}{15}\}}$
