Answer 1

Răspuns:

$\frac{ \sqrt{7} }{ \sqrt{2} } = \frac{ \sqrt{7} \sqrt{2} }{ \sqrt{2} \sqrt{2} } = \frac{ \sqrt{14} }{2}$

$\frac{ \sqrt{5} }{ \sqrt{12} } = \frac{ \sqrt{5} }{2 \sqrt{3} } = \frac{ \sqrt{5} \sqrt{3} }{2 \sqrt{3} \sqrt{3} } = \frac{ \sqrt{15} }{6}$

$\frac{ \sqrt{8} }{ \sqrt{36} } = \frac{2 \sqrt{2} }{6} = \frac{ \sqrt{2} }{3}$
