Final answer:
The expression (7 * 3) * 2 = 7 * (3 * 2) is an example of the Associative Property of Multiplication, which allows the grouping of factors to be changed without affecting the product.
Step-by-step explanation:
The property used to rewrite the expression (7 * 3) * 2 = 7 * (3 * 2) is known as the Associative Property of Multiplication. This property states that when three or more numbers are multiplied together, the way in which they are grouped does not change the product.
Therefore, you can group the numbers differently and still get the same result.
For example, multiplying 7 and 3 first, and then multiplying the result by 2, will give you the same answer as multiplying 3 and 2 first, and then multiplying the result by 7.
