)
​

Answer 1

GIVEN :

$</p><p>(\sqrt{5} + \sqrt{2} {})^{2} </p><p></p><p>$

TO DO :

Simplify the given expression

FORMULA USED :

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

SOLUTION :

$⟹(\sqrt{5} + \sqrt{2} {})^{2}$

$⟹ \: { (\sqrt{5} )}^{2} + { (\sqrt{2}) }^{2} + 2 \sqrt{5} \sqrt{2}$

$⟹5 + 2 + 2 \sqrt{10}$

$⟹7 + 2 \sqrt{10}$

ANSWER :

$⟹7 + 2 \sqrt{10}$
