x-y=13=sqrt(x)+sqrt(y)

y=sqrt(x+sqrt(x))

If 0

If 0 (a) sqrt(x)-\ sqrt(y)=\ sqrt(x-y) (b) sqrt(x)+\ sqrt(x)=\ sqrt(2x) (c) xsqrt(y)=ysqrt(x) (d) sqrt(x y)=\ sqrt(x)\ sqrt(y)

(x - y) / (sqrt(x)- sqrt(y)) = ____

If x, y, z are in A.P then 1/(sqrt(x) + sqrt(y)) , 1/(sqrt(z) + sqrt(x)) , 1/(sqrt(y) + sqrt(z)) are in

x sqrt(x)+y sqrt(y)=a sqrt(a) then find (dy)/(dx)

If 0

If 0

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