If `y` is a function of `x and log (x+y)=2xy`, then the value of `y'(0)` is

If y is a function of xand log(x+y)-2xy=0, then the value of y'(0) is (a) 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

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 log(x+y)=2xy then y'(0)=

If log(x+y)=2xy, then y'(0) is

If log_(y) x + log_(x) y = 2, x^(2)+y = 12 , then the value of xy is

If y is a function of x given by 2log(y-1)-log x-log(y-2)=0, then

If x and y satisfy the following system of equations, log x – log y = -2 , log x + 2 log y=1 then the value of xy is

log_(e)(x+y)=2xy then y'(0) is
