If $0<x, y<1$ and $\log _{x}(a)+\log _{y}(a)=4 \log _{x y}(a)$ for some $a>0, a \neq 1$, then (a) $x+y=2$ (b) $x+y=1$ (c) $x=y$ (d) $x y=a^{2}$
If $x^{y}=e^{x-y}$, then $\frac{d y}{d x}$ is: (A) $\frac{1+x}{1+\log x}$ (B) $\frac{1-\log x}{1+\log x}$ (C) not defined (D) $\frac{\log x}{(1+\log x)^{2}}$
If $x \frac{d y}{d x}=y(\log y-\log x+1)$, then the solution of the equation is (A) $y \log \left(\frac{x}{y}\right)=c x$ (B) $x \log \left(\frac{y}{x}\right)=c y$ (C) $\log \left(\frac{y}{x}\right)=c x$ (D) $\log \left(\frac{x}{y}\right)=c y$
