If` x+y=2^(y), then (dy)/(dx)`equals-

If x=y ln(xy), then (dy)/(dx) equals

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

If y=x^(x^(2)), then (dy)/(dx) equals

If 2^(x)+2^(y)=2^(x+y), then (dy)/(dx) is equal to -(2^(y))/(2^(x))(b)(1)/(1-2^(x))1-2^(y)(d)(2^(x)(1-2^(y)))/(2^(y)(2^(x)-1))

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

y=x^(x) then dy/dx equals

If (cos x)^(y)=(sin y)^(x), then (dy)/(dx) equals-
