calculeaza 2/radical7+radical5+2/radical5+radical31/radical3-1/radical7

Answer 1

Salut,

$\frac{2}{ \sqrt{7} } + \frac{ \sqrt{5 + 2} }{ \sqrt{5} } + \frac{ \sqrt{31} }{ \sqrt{3} } - \frac{1}{ \sqrt{7} } = \\ \\ \frac{2 \sqrt{7} }{7} + \frac{ \sqrt{5 \: + \: 2} }{ \sqrt{5} } + \frac{ \sqrt{9 3} }{3} - \frac{ \sqrt{7} }{7} = \\ \\ \frac{ \sqrt{7} }{7} + \frac{ \sqrt{7} }{ \sqrt{5} } + \frac{ \sqrt{93} }{3} = \\ \\\boxed{\bold{ \frac{ \sqrt{7} }{7} + \frac{ \sqrt{35} }{5} + \frac{\sqrt{93} }{3} }}$
