If `x^y=e^(x-y);` then `(dy)/(dx)` is

If x^(2y)=e^(x-y)," then "(dy)/(dx)=

If x^(y)=e^(x-y) then (a) (dy)/(dx) doesn't exist at x=1 (b) (dy)/(dx)=0 when x=1 (c) (dy)/(dx)=(1)/(2) when x=e (d) none of these

If x=e^(x/y), then (dy)/(dx) is equal to

If y=e^(x)+x then (dy)/(dx)=

If x^(y)=e^(x-y), then find (dy)/(dx)atx=1

If y=e^(x^(x)), then (dy)/(dx) is

If y= x^(e^(x)) ,then (dy)/(dx) =

If tan(x+y)=e^(x+y) , then (dy)/(dx)

if y^(x)=e^(y-x) then (dy)/(dx)
