[" Find the product : "5],[(2sqrt(5)+sqrt(5)(2sqrt(5)-sqrt(5))]quad " (ii) "(sqrt(3)+sqrt(7))^(2)

(2sqrt(7))/(sqrt(5)-sqrt(3))

Find the product of 5sqrt(2)(3+sqrt(2))(5+sqrt(2))

(2)/(sqrt(3)+sqrt(5))+(5)/(sqrt(3)-sqrt(5))=x sqrt(3)+y sqrt(5)

(1)/(2sqrt(5)-sqrt(3))-(2sqrt(5)+sqrt(3))/(2sqrt(5)+sqrt(3)) =

Evaluate (sqrt(5)-sqrt(3))/(sqrt(2)+sqrt(7))

Evaluate (sqrt(7)-sqrt(2))(sqrt(5)+sqrt(2))

(sqrt(3)-sqrt(5))(sqrt(3)+sqrt(5))/(sqrt(7)-2sqrt(5))

Simplify the following expressions . i) (5+sqrt(7))(2+sqrt(5)) ii) (5+sqrt(5))(5-sqrt(5)) iii) (sqrt(3)+sqrt(7))^(2) iv) (sqrt(11)-sqrt(7))(sqrt(11)+sqrt(7))

Simplify the following expressions. (i) (5+sqrt(7))(2+sqrt(5)) (ii) (5+sqrt(5))(5-sqrt(5)) (iii) (sqrt(3)+sqrt(7))^2 (iv) (sqrt(11)-sqrt(7))(sqrt(11)+sqrt(7))

(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(sqrt(5)+1))-sqrt(3-2sqrt(2))
