Simplify the following expressions: (i)...

Simplify the following expressions: (i)`(sqrt(3)+sqrt(7))^2` (ii) `(2sqrt(5)+3sqrt(2))^2`

Text Solution

Verified by Experts

(i)`(sqrt(3)+sqrt(7))^2`
=`{3+7}+{2(sqrt 3)(sqrt 7)}`
=`10+2{sqrt 21}`
(ii) `(2sqrt(5)+3sqrt(2))^2`
'{2*sqrt 5}^2 +{3*sqrt 2}^2+{2*2 sqrt(5)*3 sqrt(2)}
=`20+18+12 sqrt (10)= 38 + 12 sqrt(10)'`
