Answer 2

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

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 + 7 + 2 \sqrt{21}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 10 + 2 \sqrt{21}$
