What is 4d2-3d for d equals 2?
4*22 - 3*2 = 16 - 6 = 10
What is 6b4 divided by 5c4d4 divided by 3ab2 divided by 20c3d?
6b4 / 5c4d4 / 3ab2 / 20c3d Division is not associative and since there are no brackets (parentheses) the operations are evaluated from left to right. Thus 6b4 / 5c4d4 = 6/5*b4c-4d-4 6b4 / 5c4d4 / 3ab2 = 6/5*b4c-4d-4/ 3ab2 = 2/5*a-1b2c-4d-4 6b4 / 5c4d4 / 3ab2 / 20c3d = 2/5*a-1b2c-4d-4/ 20c3d = 1/50*a-1b2c-7d-5 or b2/(50ac7d5)
