Let

y=y(x)

be the solution of the differential equation

\left(2 x \log _e x\right) \frac{d y}{d x}+2 y=\frac{3}{x} \log _e x, x > 0

and

y\left(e^{-1}\right)=0

. Then,

y(e)

is equal to

View answer and explanation

Correct option: C

-\frac{3}{\mathrm{e}}

Option C (-3/e) is correct because it is the value of y(e) obtained by solving the given differential equation with the given initial condition.
