Exercise 79 Page 250

The prime factorization of a composite number is the number written as a product of its prime factors.

2^3* 3

Practice makes perfect

Let's start by recalling the definition of two important terms.

Term	Definition	Examples
Prime Number	A number that has exactly two positive factors, 1 and itself.	3, 5, 13
Composite Number	A number that is not a prime number.	4, 12, 63

We want to write the prime factorization of 24. The prime factorization of a composite number is the number written as a product of its prime factors. We will use factor pairs and a factor tree to find the desired prime factorization. The factor tree is complete when only prime factors appear in the product.
