1. i decided to do the first problem on the test for you! get out your red pen! i made a mistake what did i do wrong? explain my mistake and fix it!

The x^6 should be on the bottom because when you attempt to bring x^12 on top, you are essentially doing the equation x^6-x^12 which would equal x^-6 and if you have x^-6, you must bring it down to the denominator so the final answer for question 1 is 27/4x^6y^8
