Answer 1

Explicație pas cu pas:

$\sqrt{ \frac{5}{0.2} } + \sqrt{ \frac{5}{0.0(2)} } + \sqrt{ \frac{5}{0.000(2)} } = \\ \sqrt{ \frac{5}{ \frac{1}{5} } } + \sqrt{ \frac{5}{ \frac{2}{90} } } + \sqrt{ \frac{5}{ \frac{2}{9000} } } = \\ 1 + \sqrt{5 \times 45} + \sqrt{5 \times 4500} = \\ 1 + \sqrt{225} + \sqrt{22500} = 1 + 15 + 150 = 166$
