Question 647315: http://m1146.photobucket.com/albumview/albums/pigrabbit_8/dfe0330c.jpg.html?o=0&newest=1
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.

Question 662194: How do you simplify this expression without leaving any negative exponents?
(-3x^-1*y^5)^-1. It is a web assign question so I know there is a specific format and I've tried many different combinations but can't seem to make the y^-5 positive.
