Question

Using the Commutative Property, prove that the algebraic expressions are equivalent. In 1 sentenced, explain your result.
Expression 1: y. 3x
Expression 2: 3 xy

Answer 1

Using the Commutative Property, we can rearrange Expression 1 (y * 3x) as (3 * y) * x, which is equivalent to Expression 2 (3 * y * x), thus proving that both expressions are equivalent.
