Example: 3x * 7y = _____ ? Solution: 3x * 7y = (3x * 7)*y.....(Associative Law) = [(3*x)*7]*y = [3*(x*7)]*y.....(Associative Law) = [3*(7*x)]*y.....(Commutative Law) = [(3*7)*x]*y.....(Associative Law) = [21*x]*y = 21*(x*y).....(Associative Law) = 21xy Directions: Solve the following multiplication problems.
