Example Question #1 : Associative Property Of Multiplication
Which of the following displays the associative property of multiplication?
The associative property of multiplication states that you can multiply numbers together in any order, and the answer will not change. Therefore,
displays the associative property of multiplication since the two sides are equal no matter which set of parentheses you solve first.
Example Question #1 : Distributive Property
Simplify the expression.
Use the distributive property to multiply each term of the polynomial by
