If ` x = (2sqrt15)/(sqrt5 + sqrt3)` then evaluate ` (x+sqrt3)/(x-sqrt3) + (x + sqrt5)/(x- sqrt5)`

If x= (2sqrt(15))/(sqrt5+sqrt3) , find the value of (x+sqrt3)/(x-sqrt3)+(x+sqrt5)/(x-sqrt5).

If x = (4sqrt15)/(sqrt5 + sqrt3) then find the value of (x + sqrt20)/(x - sqrt20) + (x + sqrt12)/( x-sqrt12)

(x+sqrt5)(x-3sqrt5) =

If x= (4sqrt(15))/(sqrt5+sqrt3) , then (x+sqrt(20))/(x-sqrt(20))+(x+sqrt(12))/(x-sqrt(12))= ?

If (sqrt7-sqrt3)=1/sqrt5(sqrt(35)+x) , the value of x is:

sqrt(5)x^(2)+2x-3sqrt(5)

(x+sqrt(5))(x-3sqrt(5))=……….
