Answer 1

Sigur!

$\sqrt{ \frac{12}{5} } = \frac{ \sqrt{12} }{ \sqrt{5 =} } = \frac{2 \sqrt{3} }{ \sqrt{5} } = \frac{2 \sqrt{3} }{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{2 \sqrt{3} \times \sqrt{5} }{ \sqrt{5} \times \sqrt{5} } = \frac{2 \sqrt{15} }{ \sqrt{5} \times \sqrt{5} } = \frac{2 \sqrt{15} }{5}$
