Question

$\frac{ \sqrt{13 \: - \sqrt{11} } }{ \sqrt{13 \: + \sqrt{11} } }$
​

Answer 1

Correct Question is :

$\frac{ \sqrt{13} - \sqrt{11} }{ \sqrt{13} + \sqrt{11} }$

On solving :

$\frac{ \sqrt{13} - \sqrt{11} }{ \sqrt{13} + \sqrt{11} } \times \frac{ \sqrt{13} - \sqrt{11} }{ \sqrt{13} - \sqrt{11} } \\ \\ = > \frac{13 + 11 - 2 \sqrt{143} }{13 - 11} \\ \\ = > \frac{24 - 2 \sqrt{143} }{2} = 12 - \sqrt{143}$
