Hi, I was looking at a math book when I stumbled across a problem: Prove the following: given I am a little puzzled. How would I prove it? Using proof by counterexample? Thanks!

You can prove this using derivatives...
Okay... Is it possible without derivatives?
Why would you want a different method? First note that for all , while for all . So for all . Then note that and . For , we have So that means grows slower than does, so can never catch up. Therefore for all .
Okay, that makes sense... So we can use growth rates of functions to determine which is the largest in the end.
Use a contradiction: suppose not, that means that would imply but this is obviously false since
