Question

1) (√5+√2)^2
2) √11-√5)^2

Answer 1

1)5+2+2root 10=7+2√10
2)11+5-2√55=16-2√55

Answer 2

Heya!!
Here is your answer :-
1) (√5+√2)^2
2) √11-√5)^2

Answers:-
1)
$( \sqrt{5} + \sqrt{2} ) ^{2}$
We have to simplify it.
We can see that it is in the form of:-
${(a + b)}^{2}$
Upon comparing these two we can see that,
a=√5, b=√2
Now this is an identity that:-
$(a + b) ^{2} = a {}^{2} + {b}^{2} + 2ab$
The rest solution is continued in the picture.



Hope it helps you.
