You found the x value for which lnx/x is a maximum. To find that actual maximum value you need to sub x=e into the original equation. Doing that you get 1/e as required. =) So yes you did it right, but you just didn't finish the question. Make sure you do in the HSC.

Heya! Daniel? It's Oscar. Hope you're enjoying the start of your holidays =) Did you go to the final assembly today?
