Which expression correctly demonstrates the commutative property of multiplication?

15 (X + 4) = 15 (X • 4)
15 • x • 4 = 4 + 15 + x
15 • (x) • 4 = 4 • 15 • (x)
x + 4 + 15 = 15 + 4 + x

1 answer

The expression that correctly demonstrates the commutative property of multiplication is:

15 • (x) • 4 = 4 • 15 • (x)

The commutative property of multiplication states that changing the order of the factors does not change the product. In this case, both sides of the equation represent the same product, demonstrating this property.
