`(sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5)` Is equal to

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

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

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

show that (sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))times(sqrt(7)-sqrt(5))/(sqrt(7)-sqrt(5)) =frac{(sqrt(7)-sqrt(5))^(2)}{2}

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

Simplify (sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))+sqrt(35)
