So the question is:
Suppose p is a prime and n is a positive integer. Find a formula for |(Z/p^nZ)^x|.
I do not know what this notation means, what do the | | mean around this? I know that the other part is the set of all the units in Z/p^nZ, but I have no idea what the | | mean. I don't think it's absolute value. Is it just the elements of it? Thanks for the help.
