" Prast that "2-3sqrt(5)" is an itration no: "

sqrt(5)x^(2)+2x-3sqrt(5)

The simplest rationalising factor of 2sqrt(5)-sqrt(3) is (a) 2sqrt(5)+\ 3 (b) 2sqrt(5)+sqrt(3) (c) sqrt(5)+sqrt(3)\ \ (d) sqrt(5)-sqrt(3)

(2sqrt3 + sqrt5)(2sqrt3 - sqrt5)

" 3." (2+sqrt(5))(2+sqrt(5)) " is: "

Evaluate : ( sqrt(2) - sqrt(3) + sqrt(5) )times ( sqrt(2) + sqrt(3) + sqrt(5) )

(sqrt(5)+sqrt(3))((3sqrt(3))/(sqrt(5)+sqrt(2))-sqrt(5)/(sqrt(3)+sqrt(2))) is equal to :
