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

Simplify (sqrt(7)+sqrt(2))(sqrt(7)-sqrt(2))

(sqrt(7)-sqrt(5))^3 - (sqrt(7)+sqrt(5))^3

Rationales the denominator and simplify: (sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2))( ii) (5+2sqrt(3))/(7+4sqrt(3))

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

Simplify (1)/(sqrt(6)-sqrt(5))+sqrt(6)-sqrt(5)

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

simplify (sqrt(7)+sqrt(2))^(2)

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

If sqrt(35)=5.9160, then the value of (sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5))

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