[(x9)/(x^29)][(1)/(x+3)]
I got (6x)/(x+3) for answer.
[(2)/(y3)]+[£¨4£©/(3y)]
I got (2)/(y3) for answer.
I'm not sure about the answers, please check them for me and correct me!
THANKS A LOT!

The first is wrong. I am not certain about the second.
I will be happy to check your work. To do the first one, multiply the second term only by (x3)/(x3) 
I did mutiply the second term by (x3)/(x3), but when I simplify it, I got mess up.
