( √5 + √2 )²

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

( √5 + √2 )²

⇒ ( √ 5 )² + ( √ 2 )² + 2( √5 × √ 2 )

⇒ 5 + 2 + 2√( 5 × 2 )

⇒ 5 + 2 + 2√10

⇒ 7 + 2√10

Step-by-step explanation:

Given,

( \sqrt{5}  +  \sqrt{2} ) ^{2}

By the formula (a+b)^2 = a^2+b^2+2ab

 \sqrt{5}^{2}  +  \sqrt{2}  ^{2}  + 2( \sqrt{5} )( \sqrt{2} )

5 + 2 + 2 \sqrt{10}

7 + 2 \sqrt{10}
