Evaluate :

`( sqrt(5) + sqrt(7 ) ) /( sqrt(5) - sqrt(7 ) )`

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

5/(sqrt(5)-sqrt(7))

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

7/(sqrt5-sqrt3) =

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

What is the value of (1/(sqrt(9) - sqrt(8)) - 1/(sqrt(8) - sqrt(7)) + 1/(sqrt(7) - sqrt(6)) - 1/(sqrt(6) - sqrt(5)) + 1/(sqrt(5) - sqrt(4))) ?

Evaluate (sqrt(7)-sqrt(5))/ (sqrt(7)-sqrt(5))

Evaluate : (1+sqrt7)^5+(1-sqrt7)^5

Evaluate (4+sqrt(5))(sqrt(3)-sqrt(7))

Find (x+a)^(5)+(x-a)^(5) . Hence, evaluate (sqrt(6)+sqrt(7))^(5)+(sqrt(6)-sqrt(7))^(5)
