Read about Prime Factorization (the Fundamental Thm of Arithmetric) on the last page of the (linked) Ch 3 summary handout, which is also on our Handout Page and was handed out in class.
If the notation in the Prime Factorization does not make sense, find the prime factorization of some 3-4 digit numbers (remember them "factorization trees") to help you make sense of the notation. Remeber ∑ is for sum while ∏ is for product. Nothing to hand in.
