Proof Regarding Primes to a Power

So I have the question:

I know that if p|a^n then p|a(a)(a)...(a) n times and therefore p|a.

I'm having some trouble finding a property that can either prove or disprove that p^n|a^n assuming p|a^n. Could someone point me in the right direction? Thank you so much.

Re: Proof Regarding Primes to a Power

Well , you are very close to proving it , use your result p|a , you just need one more truth.


then for some integer c ,
