Question 135337: Can someone point me to the right direction with this problem?
Use a combination of rules and exponents to simplify each expression.
y to the negative 8 power times y to the 5 power times y to the negative 2 power.
So far I come up with y to the neg. 8 power over 1 = 1 over y to the 8 power. Does it just become positive y to the 8 so you can begin to times it by the y to the 5 power and so forth? I would like to know if I am doing the problem right.
Anyones response greatly appreciated.

Simplify:
y%5E%28-8%29%2Ay%5E5%2Ay%5E%28-2%29 The bases are the same (y) so just add the exponents:
y%5E%28-8%29%2Ay%5E5%2Ay%5E%28-2%29+=+y%5E%28%28-8%2B5%2B%28-2%29%29%29=y%5E%28-5%29+=+1%2Fy%5E5
