Answer 1

Answer:

8+2*root10=2 (4+root10)

Step-by-step explanation:

(a+b)^2= a^2+b^2+2ab

putting the eqn

Answer 2

Answer:-

$\bf \: {( \sqrt{5} + \sqrt{2} })^{2} \\ \\ \bf \:by \: \: using \: \: formula \\ \\ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ \\ now \\ \\ \bf \: {( \sqrt{5} + \sqrt{2} })^{2} = {( \sqrt{5} })^{2} + 2( \sqrt{5} )( \sqrt{2} ) + {( \sqrt{2} })^{2} \\ \\ \bf \: {( \sqrt{5} + \sqrt{2} })^{2} = 5 + 2 \sqrt{10} + 2 \\ \\ \bf \: {( \sqrt{5} + \sqrt{2} })^{2} = 7 + 2 \sqrt{10}$
