well, i first changed 2/3 and 1/3 powers on my paper to the cubed root of x squared, and the cubed root of -9x. then, i cubed everything, which, now that i think about it, is kind of retarded. anyway, i came up with some weird answers like 54i and 53.543i, and i could never figure out the problem. it doesn't really matter because at the final i had an average of 101.2 and it doesn't matter what grade i get on it. but i figure since i'm student of the semester i should definitely know how to do this.
