X^y = e​​(x-y) = e^x / e^y
X^y  *  e^y = e^x
(xe)^y = e^x
Take log on both sides of above eq
y * log (xe) = x ---(1)
Differentiate both side wrt x
dy/dx * log x. +  ey/xe. =  1
dy/dx. =  1 – y/x
                 Log(xe)
 
            = x-y / x*log (xe)
From question we know x-y = y * log x
    So   dy/dx=         y*log x
                               X* Log(xe)
From (1) y*log(xe)=x so y/x=1/log(ex), substitute this is above eq to get answer
