Question

8 plus 2 root 15 ka whole root

Answer 1

$\sqrt{8 + 2 \sqrt{15} } \\ \\ \sqrt{3 + 5 +( 2 \sqrt{3 \times 5}) } \\ \\ \sqrt{ (\sqrt{3} )^{2} + (\sqrt{5}) ^{2} + (2 \sqrt{3 \times 5} )} \\ \\ \\ \\ \\ by \: formula \: {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ \\ \\ \\ here \\ \\ \sqrt{( \sqrt{3} ) ^{2} + ({ \sqrt{5} )}^{2} + (2 \sqrt{3 \times 5} )} \\ \\ \sqrt{( \sqrt{3} + \sqrt{5}) ^{2} } \\ \\ ( \sqrt{3} + \sqrt{5} ) ^{2 \times \frac{1}{2} } \\ \\ \sqrt{3} + \sqrt{5}$

Answer 2

5+3+2root(5*3)
(root5)^2+(root3)^2+2root5*root3
(root5+root3)^2
so
root(5+root3)^2
root5+root3
