Question

(√5+√2) (√5+√2). Simplify

Answer 1

Step-by-step explanation:

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

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

by using identity

(a+b)²=a²+b²+2ab

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

$5 + 2 + 2 \sqrt{10}$

$7 + 2 \sqrt{10}$
