If ln(x+y)=2x y , then y '(0)?

If x^(y)=y^(x) then (dy)/(dx)= ... (A) (y(x log y-y))/(x(y log x-x)) (B) (y(y log x-x))/(x(x log y-y)) (C) (y^(2)(1-log x))/(x^(2)(1-log y)) (D) (y(1-log x))/(x(1-log y))

If x^y = y^x , then dy/dx = ......... A) frac{y(x log y - y)}{x(y log x -x)} B) frac{y(y log x - x)}{x(x log y -y)} C) frac{y^2 (1- log x)}{x^2 (1- log y)} D) frac{y(1- log x)}{x(1-log y)}

If ln(ln x-ln y)=e^(x^(2)y)(1-ln x) , then y'(e) equals

If y is a function of x and ln(x+y)-2x y=0, then the value of y^(prime)(0) is equal to 1 (b) -1 (c) 2 (d) 0

If y is a function of x and log(x+y)-2xy=0 then the value of y(0) is equal to (a)1(b)-1( c) 2( d) 0
