Best ResponseYou've already chosen the best response.0alright let's take it a step at a time :) 54 = 9 x 6 = 3x3x3x2, so : \[54 =( 3^3 )(2)\] \[m^9 = (m^3)(m^3)(m^3)\] so you can write it down as : \[m^9 = (m^3)^3\] and \[n^5 = (n^3)(n^2)\] now let's write these down under the cubic root ^_^ : \[\sqrt[3]{(3)^3(2)(m^3)^3(n)^3(n)^2}\] now we can take the ones that have a cubic power out , so the answer is : \[= 3m^3n^3\sqrt[3]{2n^2}\] understand it ? ^_^

Best ResponseYou've already chosen the best response.0you have a cubic root right? so m^3's power which was also another(3) was cancelled ^_^
