The correct answer is d. All of the above.
Each of the expressions demonstrates the Commutative Property of Multiplication, which states that changing the order of the factors does not change the product. Here’s how each expression illustrates this:
-
a. \(7 * x * 3 = 3 * 7 * x\) shows that the order of \(7\), \(x\), and \(3\) can be changed without affecting the product.
-
b. \(4 * y * 2 = 4 * 2 * y\) shows that the order of \(4\), \(y\), and \(2\) can also be rearranged.
-
c. \(5 * z * 6 = 6 * 5 * z\) illustrates that rearranging \(5\), \(z\), and \(6\) yields the same result.
Therefore, all provided expressions correctly demonstrate the Commutative Property of Multiplication.
