Question

√7+√2√10=?
$\sqrt{7 + 2 \sqrt{10 } } = what$

Answer 1

$= > \frac{ \sqrt{7} + \sqrt{2 + \sqrt{10} } }{ \sqrt{ \sqrt{7} + \sqrt{2 + \sqrt{10} } } } \\ = > \frac{ \sqrt{ \sqrt{7} + \sqrt{2 + \sqrt{10} } } \times \sqrt{ \sqrt{7} + \sqrt{2 + \sqrt{10} } } } { \sqrt{ \sqrt{7} + \sqrt{2 + \sqrt{10} } } } \\ = > \sqrt{ \sqrt{7} + \sqrt{2 + \sqrt{10} } }$
