Question

find :

(√5 + √2)^2

...............​

Answer 1

Answer:

hey mate here's ur ans

(√5+√2)^2

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

(√5)^2+2×(√5)(√2)+(√2)^2

5+2√10+2

7+2√10 is the ans

hope it helps u:)

Answer 2

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

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

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

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

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

$= 7 + 2 \sqrt{10}$

hope it helps u...!!
