Also, since you haven't taken the limit yet, you should not get rid of the "lim" symbol.

limit of ln as x goes to infinitywhat you typed is equivalent to: [tex]\displaystyle \lim_{x\to \infty}\dfrac{[ln(x)]^2}{x}[/tex] Did you intend [tex]\displaystyle \lim_{x\to \infty}[ln(x)]^{\frac{2}{x}} \ ?[/tex]
