hope it will be helpful

Answer 2

Solution :-

$( \sqrt{2} + \sqrt{8} ) {}^{2} \\ ( \sqrt{2} ) {}^{2} + ( \sqrt{8} ) {}^{2} + 2 \times \sqrt{2} \times \sqrt{8} \\ 2 + 8 + 2 \sqrt{16} \\ 10 + 2 \times 4 \\ 10 + 8 = 18 \: ans$

Hint:

$( \sqrt{n} ) {}^{2} = n$

Example :

$(\sqrt{3}) {}^{2} = 3 \\ \\ (\sqrt{7} ) {}^{2} = 7 \: \: etc$
