Answer 1

Hey friend,
Here is the answer you were looking for:
${( \sqrt{3} + \sqrt{7} ) }^{2} \\ \\ using \: the \: identity \\ {(a + b)}^{2} = {(a)}^{2} + {(b)}^{2} + 2ab \\ \\ = {( \sqrt{3} )}^{2} + {( \sqrt{7} )}^{2} + 2 \times \sqrt{3} \times \sqrt{7} \\ \\ = 3 + 7 + 2 \sqrt{21} \\ \\ = 10 + 2 \sqrt{21}$

Hope this helps!!!
