I am not really sue where to go from here. Do I find the cube root of 423 first the mulitiply by power of 8 or the other way around? thank very much for all your help on this. this prolbem is from an online homework problem. it is not out of a book. I am currently in a Algebra II class on Univeristy Of Phoenix. thank you Answer by jim_thompson5910(28478)   (Show Source): You can put this solution on YOUR website! Start with the given expression. Factor 432 into . Note: 216 is a perfect cube Factor into . Break up the root. Take the cube root of 216 to get 6 Take the cube root of to get Rearrange the terms and multiply So
