This. Pretty much with complexity analysis, you factor out any constants and only look at the term of complexity with the highest growth rate, so you end up with 1 < ln n < n < nª < 2^n (this can be extended indefinitely by replacing the n in the last case with anything to the right of n, but in practice, these are the only ones that matter.
