sequences and series - Evaluation $lim_{nto infty}frac{n^{log m}}{m^{log n}}$




Evaluate where $m>1$ is constant




$$\lim_{n\to \infty}\frac{n^{\log m}}{m^{\log n}}$$




I tried to use L'Hopital rule but it didn't work.



I have no idea how to evaluate this limit. Can you help me with that?


Answer



The sequence is constant. Take the logarithm of each part and compare.
