Answer 2

$\frac{5 \times \sqrt{2 \times 2} }{5} = simplificam \\ \sqrt{2 \times 2} = \sqrt{4} = 2$
$\frac{ \sqrt{2 \times 2} }{5} = \frac{ \sqrt{4} }{5} = \frac{2}{5}$
$\frac{2 \times \sqrt{5 \times 2} }{5} = \frac{2 \sqrt{10} }{5} = \\ \frac{ \sqrt{ {2}^{2} \times 10} }{ 5} = \frac{ \sqrt{40} }{5} = \frac{6.32}{5}$
