Find:- `(sqrt7-sqrt5)^2`

(5+sqrt7)(2+sqrt5)=?

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

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}

Rationalize 3/(2sqrt7+sqrt5)

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

By how much does 5sqrt(7) - 2sqrt(5) exceed 3sqrt(7) - 4sqrt(5) ?

Evaluate the product of [(sqrt5+sqrt6+sqrt7)/2^(1/4)][(sqrt6+sqrt7-sqrt5)/2^(1/3)][(sqrt5+sqrt7-sqrt6)/2^(3/4)][(sqrt5+sqrt6-sqrt7)/2^(2/3)]

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

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