Best ResponseYou've already chosen the best response.0i tried using this http://openstudy.com/study#/updates/513cdcd0e4b029b0182b5689 and i did 36  ar 2304 = ar^4 2304 = ar * r^3 2304 = 36 * r^3 2304 = r^3????????

Best ResponseYou've already chosen the best response.0your second to last step looks correct 2304 = 36 * r^3 what happened to the 36 in the next step? did you mean to divide the 2304 by that amount?

Best ResponseYou've already chosen the best response.0\[r^3=64=\left( 4 \right)^3,r=4\]
