Which of the following demonstrates the associative property of multiplication?

The associative property of multiplication states that when you multiply three or more numbers together, the way in which the numbers are grouped does not change the product. In mathematical terms, this can be expressed as (ab)c = a(bc). This indicates that regardless of whether you first multiply 'a' and 'b' or 'b' and 'c', the final product will remain the same.

In this choice, the focus is on reassociating the factors without altering the overall multiplication result, which is a defining characteristic of the associative property. It highlights the flexibility in grouping factors when performing multiplication, showcasing that the order in which the operations are performed does not affect the outcome.

The other options represent different mathematical principles. For example, one option suggests a property of addition, and others involve expressions that may illustrate the commutative property of addition or elements of distribution. However, these do not exemplify how multiplication remains consistent irrespective of how the numbers are grouped, which is the essence of the associative property.
