Answer 2

$\large{\underline{\underline{ \bf{⎆Question:-}}}}$

$\tt{To\: evaluate : \sqrt{315 + \sqrt{66 + \sqrt{225} } } }$

$\large{\underline{\underline{ \bf{☂ Solution:-}}}}$

$\longmapsto\tt{ \sqrt{315 + \sqrt{66 + \sqrt{225} } } }$

$\longmapsto\tt{ \: \sqrt{315 + \sqrt{66 + \sqrt{15 \times 15} } } }$

$\longmapsto\tt{ \sqrt{315 + \sqrt{66 + 15} } }$

$\longmapsto\tt{ \sqrt{315 + \sqrt{81} } }$

$\longmapsto\tt{ \sqrt{315 + \sqrt{9 \times 9} } }$

$\longmapsto\tt{ \sqrt{315 + 9} }$

$\longmapsto\tt{ \sqrt{324} }$

$\longmapsto\tt{ \sqrt{18 \times 18} }$

$\longmapsto\tt{ 18}$

$\tt{Hence \: , \sqrt{315 + \sqrt{66 + \sqrt{225} } } = 18}$
