प्रश्न

Choose the correct alternative.

The solution of `x dy/dx = y` log y is

पर्याय

  • y = aex

  • y = be2x

  • y = be-2x

  • y = eax

उत्तर

The solution of `x dy/dx = y` log y is y = eax

`x dy/dx = y` log y

∴ `dy/(ylogy) = dx/x`

Integrating on both sides, we get

`int dy/(y logy) = int 1/x dx`

∴ log log(y)= log x + log a

∴ log log(y)= log xa

∴ log(y)= ax

∴ y = eax
