" If `2^(x)+2^(y)=x+y, then (dy)/(dx)` is equal to "

If 2^(x)+2^(y)=2^(x+y) then (dy)/(dx) is equal to

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

If (y/x) + (x/y)=2 , then (dy)/(dx) is equal to

If x^(2)+y^(2)=4, then y(dy)/(dx)+x is equal to

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

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