1. The problem statement, all variables and given/known data
Find the following limit:
\lim_{n \rightarrow \infty}\frac{n}{\log_{10}{n}}
3. The attempt at a solution
It's easy to find the limit using L'Hospital rule (after having used Heine theorem to transform the sequence into a function):
\lim_{x \rightarrow \infty}\frac{x}{\log_{10}{x}} = \lim_{x \rightarrow \infty}\frac{1}{\frac{1}{x\log{10}}} = +\infty
Is there any way of solving it without L'Hospital rule?
If I was to use the definition, then for every K, there should be such n_0 that for every n>n_0, (n/log_10(n)) > K. But I don't know how to solve this inequality. Any help would be greatly appreciated, thanks in advance!
