Let p be a prime number. Find all roots of x^(p1) in Z_p
I have this definition. Let f(x) be in F[x]. An element c in F is said to be a root of multiplicity m>=1 of f(x) if (xc)^mf(x), but (xc)^(m+1) does not divide f(x). I'm not sure if I use this idea somehow or not.

I think Fermat's Little Theorem will be useful here.
