" (v) "(4)/(sqrt(5)+sqrt(3))

Rationalize the denominatior and simplify to find the value of (4)/(sqrt(5) + sqrt(3)) (Given : sqrt(5) = 2.236 and sqrt(3) = 1.732)

(1)/(4sqrt(3)-3sqrt(5))

Rationalize the denominator and simplify to find the value of 4/(sqrt(5)+sqrt(3)) , given that sqrt(5)=2.236 and sqrt(3)=1.732

Rationalise the denominator and simplify: (i) (4sqrt(3)+5sqrt(2))/(sqrt(48)+\ sqrt(18)) (ii) (2sqrt(3)-\ sqrt(5))/(2\ sqrt(2)+\ 3sqrt(3))

If x=(4sqrt(15))/(sqrt(5)+sqrt(3)) then the value of (x+sqrt(20))/(x-sqrt(20))+(x+sqrt(12))/(x-sqrt(12)) is

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

Find (x+a)^(3)-(x-a)^(3) . Hence evaluate (sqrt(5)+sqrt(4))^(3)-(sqrt(5)-sqrt(4))^(3)
