a marathon map, you'd be the first to mod it

if it's too long, just ignore. thanks

Opened!

Solve the following question and you can get 2 free mods from me!

Suppose that p is a given prime. For all integer x that satisfies p|(x^n -1) ,we have (p^2)|(x^n -1).
Find out all the positive integer n. The answer should contain the prime p.
Proof is required.

Hi

,

I'll try something:

(1+p)^n=1 modulo p
(1+p)^n=1+np modulo p^2

So if n is such that for all integer x, p|(x^n -1) implies (p^2)|(x^n -1) then we must have 1+np=1 modulo p^2 then we must have p|n.

Let's proove that n=p works:
If x is a multiple of p then x^p=0 modulo p.
If x is not a multiple of p then x^p=x modulo p.
So, x^p=1 modulo p if and only if x=1 modulo p.
Or, if x=1 modulo p then x=1+kp with k an integer.
So, x^p=1+kp^2 modulo p^2
-> x^p =1 modulo p^2

So, x^p=1 modulo p implies x^p=1 modulo p^2.

Now let's proove that the property is verified for every n multiple of p.
Let's take n=kp with k an integer. Then we have:
x^n=1 modulo p
-> (x^k)^p=1 modulo p
-> (x^k)^p=1 modulo p^2 (because we jsut proove that x^p=1 modulo p implies x^p=1 modulo p^2)
-> x^n=1 modulo p^2

So, i just prooved that if n verifies your property then n is a multiple of p and after that, i prooved that if n is a multiple of p then it verifies your property.
So, the answer is: all the n mulitples of p (including 0) verifies: for all integer x, p|(x^n -1) implies (p^2)|(x^n -1).

I accept this solution so you can get 2 mods (or tickets) from me!
Feel free to post your map link :3

And also, the queue is closed for a while!
