Please help with number 88. I'm confused on how I should deal with the negative exponent. I know I have to switch it and put a 1 over but then the whole problem just became very, very confusing. I got 20x and I think the answer is wrong. Don't ask me how I got that, I probably skipped an important step or did something wrong. Thank you for your help.
