Quote from "Roberts91" »Ok I got this problem and since I dont know how to do exponents on the keyboard without confusing you I will just write out the word of the number when I do that it just simply means an exponent
2m^4 * n^-2 * (2n^4)^3 (I just put the * in there for clarity it means multiply)
The answer I got was 12m^4 * n^10
but the answer that is in the answer chart is 16m^4 * n^10
Can anyone explain what I did wrong? Thanks!
