challange question

by tozturk90 Sun Aug 31, 2014 7:45 am

If x = pn and nn = n + n, where x and n are positive integers and p is a prime number, how many positive factors does x have?
why x has 3 factors. if n=2 how p would be 1 and p?
X would be equal only p2

I don't get the question:

nn = n + n

That's not ever true.
