" (i) "(sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))+sqrt(35)

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

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

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

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

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

(sqrt7-sqrt5)/(sqrt7+sqrt5)

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

Evaluate : (sqrt(7)+sqrt(5))/(sqrt(7)+sqrt(20)+sqrt(28)-sqrt(5)-sqrt(80))
