Answer 1

Resposta:

$\sqrt{\dfrac{4}{25} } +\bigg\{ 0,1 + \bigg[ \bigg( -\,\dfrac{3}{12} \times \dfrac{4}{3} \bigg) -\,\dfrac{1}{4} \bigg] -\, \dfrac{2}{5} \bigg\}$

${\dfrac{2}{5} +\bigg\{ \dfrac{1}{10} + \bigg[ -\,\dfrac{1}{3} -\,\dfrac{1}{4} \bigg] -\, \dfrac{2}{5} \bigg\}$

${\dfrac{2}{5} +\bigg\{ \dfrac{1}{10} + \bigg[ -\,\dfrac{4}{12} -\,\dfrac{3}{12} \bigg] -\, \dfrac{2}{5} \bigg\}$

${\dfrac{2}{5} +\bigg\{ \dfrac{1}{10} -\,\dfrac{7}{12} -\, \dfrac{2}{5} \bigg\}$

${\dfrac{2}{5} +\bigg\{ \dfrac{6}{60} -\,\dfrac{35}{60} -\, \dfrac{24}{60} \bigg\}$

${\dfrac{2}{5} +\bigg\{ \dfrac{-\,53}{60} \bigg\}$

${\dfrac{2}{5} \, - \dfrac{53}{60}$

$\dfrac{24}{60} -\, \dfrac{53}{60}$

$-\,\dfrac{29}{60}$
