Answer 1

Step-by-step explanation:

This is simple

(√7+√3)^2.

The formula is (a+b)^2

(√7)^2+ (√5)^2+ 2*√7*√5

7+5+ 11.83 = 23.83

Answer 2

• Step-by-step explanation:

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

• Using Identity (a + b)²

$(a + b) ^{2} = {a}^{2} + 2ab + {b}^{2}$

$(\sqrt{7} + \sqrt{3})^{2} = (\sqrt{7} ) ^{2} + 2( \sqrt{7} )( \sqrt{3} ) + ( \sqrt{3} ) ^{2} \\ = 7 + 2 \sqrt{21} + 3 \\ = 10 + 2 \sqrt{21}$
