State the name of the property illustrated: (6 • 3) • 9 = 6 • (3 • 9)
검증된 단계별 안내1
Identify the operation involved in the expression. Here, the operation is multiplication, denoted by the symbol \( \cdot \).
Observe how the grouping of the numbers changes in the equation: the first grouping is \( (6 \cdot 3) \cdot 9 \) and the second grouping is \( 6 \cdot (3 \cdot 9) \).
Recall the property that states that when multiplying three or more numbers, the way in which the numbers are grouped does not affect the product. This property is known as the Associative Property of Multiplication.
Write the general form of the Associative Property of Multiplication: \( (a \cdot b) \cdot c = a \cdot (b \cdot c) \), where \(a\), \(b\), and \(c\) are any real numbers.
Conclude that the given equation \( (6 \cdot 3) \cdot 9 = 6 \cdot (3 \cdot 9) \) illustrates the Associative Property of Multiplication.

Associative Property of Multiplication
This property states that when multiplying three or more numbers, the way in which the numbers are grouped does not affect the product. In other words, (a • b) • c = a • (b • c). The example (6 • 3) • 9 = 6 • (3 • 9) illustrates this property clearly.
