 Question 20180: Ok we are doing a thing on mononials and i am so not geting it. like how do you do a/awith an exponent of 4???/or 12m/15m ???????? 6r/15rs i don't get any of this please help!!!!!!!Answer by mmm4444bot(95)   (Show Source): You can put this solution on YOUR website!Hello There: From the looks of your post, I am guessing that you are supposed to simplify an expression that involves one monomial divided by another monomial. a/a^4 This can be thought of as: a/(a*a*a*a) (The asterisks mean multiplication.) The one "a" in the numerator cancels with one of the "a"s in the denominator. This is because a/a = 1. a/a^4 = 1/a^3 ---------------- 12*m/(15*m) This can be thought of as: (12/15)*(m/m) Of course, m/m = 1, so we have: 12/15 This fraction can be reduced because the numerator and denominator each contain a factor of 3. 12/15 = 4/5 ---------------- 6*r/(15*r*s) Again, the "r"s cancel because r/r = 1. 6/(15*s) The fraction 6/15 can be reduced for the same reason as the last problem. 6/15 = 2/5 This leaves us with: 2/(5*s) ~ Mark
