1. ## Induction problem

I need to prove with induction on n that every natural number with 3^n number of digits, is divided in 3^n.

I'm very new in this subject, I don't know even how to start.

Thanks for any kind of help

You need to double check your question!
221 has $3^1$ digits but 221 is not divisible by $3^1$!
So it appears not to be true as posted.
