Answer
Commutative Property of Multiplication
Work Step by Step
RECALL:
The commutative property of multiplication states that for any real numbers $a$ and $b$,
$a \cdot b = b \cdot a$
$(6\cdot9) \cdot 2 = 2 \cdot (6\cdot9)$
Thus, the given expression illustrates the commutative property of multiplication.
