Explicație pas cu pas:

$\frac{3}{ \sqrt{6} } = \frac{3}{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } = \frac{3 \sqrt{6} }{2} = \frac{ \sqrt{6} }{2}$

$\frac{4}{ \sqrt{2} } = \frac{4}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{4 \sqrt{2} }{2} = 2 \sqrt{2}$

$\frac{10}{3 \sqrt{5} } = \frac{10}{3 \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{10 \sqrt{5} }{15} = \frac{2 \sqrt{5} }{3}$

$\frac{3}{ \sqrt{75} } = \frac{3}{5 \sqrt{3} } = \frac{3}{5 \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{3 \sqrt{3} }{15} = \frac{ \sqrt{3} }{5}$

$\frac{8}{ \sqrt{200} } = \frac{8}{10 \sqrt{2} } = \frac{4}{5 \sqrt{2} } = \frac{4}{5 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{4 \sqrt{2} }{10} = \frac{2 \sqrt{2} }{5}$
