Question

calculati 5∛0.027 -(²*²√(0.0016)-²

Answer 1

$\displaystyle 5\sqrt[3]{0,027} - (\sqrt[2\times2]{0,0016})^2 = \\ \\ 5\sqrt[3]{ \frac{27}{1000}} - \left(\sqrt[2\times2]{ \frac{16}{10000}}\right)^2 = \\ \\ =5 \frac{3}{10} - \left(\sqrt[2]{ \frac{4}{100}}\right)^2 = \frac{15}{10} - \left(\pm \frac{2}{10}\right)^2 =\\ \\ =\frac{15}{10} - \frac{4}{100}=\frac{150}{100} - \frac{4}{100}=\frac{150-4}{100} =\boxed{\frac{146}{100}}$
