Wow, it has been awhile! China has been fun, but now it is time to get back to the states and also math work! Here is a problem that has been giving me some problems. It reads: [tex] \prod [/tex] from i=1 to n, pi^ai for each i is the canonical representation of a, deduce a formula for the sum of squares of the positive divisors of a. I know what the canonical representation is, so would i just plug in numbers for n, and then from the output just make up a [tex] \sum [/tex] formula? Could anyone provide guidance?
