Rationalise the denominator 1/√5+√6-√11

Answer 1

Heya Friend ✋✋✋

$\frac{1 \times \sqrt{5} }{ \sqrt{5} \times \sqrt{5} } + \frac{ \sqrt{6} \times \sqrt{11} }{ \sqrt{11 \times \sqrt{11} } } \\ = \frac{ \sqrt{5} }{5} + \frac{ \sqrt{66 } }{11} \\ = \frac{11 \sqrt{5} + 5 \sqrt{66} }{55}$
Hope it helps
