`(sqrt7+sqrt5)xx(sqrt7-sqrt5)`

(sqrt7-sqrt5)/(sqrt7+sqrt5)

If (sqrt7-sqrt5)/(sqrt7+sqrt5)=a+bsqrt(35) , then the value of (a - b) is

(1+sqrt2)/(sqrt5+sqrt3)= ((1+sqrt2)xx(sqrt5-sqrt3))/((sqrt5+sqrt3)xx(sqrt5-sqrt3))=

(sqrt7-sqrt6)/(sqrt7+sqrt6)-(sqrt7+sqrt6)/(sqrt7-sqrt6)=

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

If sqrt(35)=5.9160, then the value of (sqrt(7)+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}
