I was RIGHT!! This is the way the problem could have been stated:
%28%28y%5E5%29%5E3%29%2F%28%28y%5E3%29%5E2%29%29 over %28y%5E4%29%5E4

When you raise a power to a power, you MULTIPLY exponents! (By the way, if you need help with the Laws of Exponents, please see my Lesson Plan on algebra.com, or go to my own website by clicking on my tutor name "rapaljer", then look for "MATH IN LIVING COLOR," then "Basic Algebra", then Chapter 2.)

%28y%5E15%29%2F%28y%5E6%29 over y%5E16

When you divide, you must SUBTRACT exponents:
%28y%5E9%29 over y%5E16

%28y%5E9%29%2F%28y%5E16%29+

When you divide, again you SUBTRACT exponents:
y%5E%289-16%29+=+y%5E%28-7%29

When you have a negative exponent, this means y%5E%28-7%29=1%2F%28y%5E7%29+
