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

7/(sqrt5-sqrt3) =

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

(sqrt7-sqrt5)/(sqrt7+sqrt5)

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

The value of (2 sqrt10)/(sqrt5+ sqrt2- sqrt7)- sqrt(( sqrt5-2)/(sqrt5+2))-3/(sqrt7-2) is :- (2 sqrt10)/(sqrt5+ sqrt2- sqrt7)- sqrt(( sqrt5-2)/(sqrt5+2))-3/(sqrt7-2) का मान है :

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

Simplify (2/7-5/sqrt7)/(sqrt7-1/sqrt7)

Simplify each of the following : (i)(sqrt(2)+1)/(sqrt(2)-1)+(sqrt(2)-1)/(sqrt(2)+1)" "(ii)(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))" "(iii)(2)/(sqrt(5)+sqrt(3))+(1)/(sqrt(3)+sqrt(2))-(3)/(sqrt(5)+sqrt(2))" "(iv)(sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5))-(sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))
