The Associative Property of Multiplication states that the grouping of numbers does not affect the product. This means that when multiplying three or more numbers, you can change the grouping without changing the result.
For the expression \( p \cdot (q \cdot r) \), you can use the associative property to rewrite it as:
\[ (p \cdot q) \cdot r \]
So, the expression can be rewritten as \( (p \cdot q) \cdot r \).
