Simplify `y=(sqrt(a)+sqrt(x))/(sqrt(a)-sqrt(x))`

if y=(sqrt(a+x)-sqrt(a-x))/(sqrt(a+x)+sqrt(a-x)) find the value of (dy)/(dx)

y=sqrt(x+sqrt(x))

Evaluate (sqrt(x)+sqrt(y))(sqrt(x)-sqrt(y))

If e^(y)=(sqrt(1+x)+sqrt(1-x))/(sqrt(1+x)-sqrt(1-x))," then "(dy)/(dx)=

Simplify (x-sqrt2)(x+sqrt2)

given x=(sqrt(7)+sqrt(3))/(sqrt(7)-sqrt(3)),y=(sqrt(7)-sqrt(3))/(sqrt(7)+sqrt(3)) find the value of x^(4)+y^(4)+(x+y)^(4)

If x=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) and y=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) then the value of x^(2)+xy+y^(2)
