Indeed it is D. You can guess and check if you want. You'll eventually get your answer.
OpenStudy (anonymous):
its d?? really
OpenStudy (goldphenoix):
Yes. You want proof? |dw:1373837174597:dw|
OpenStudy (goldphenoix):
When you multiply a variable by a same variable that has an exponent:
ex: a^2 * a^3, you simplify add the exponent.
So you would get a^5.
If you were dividing a^2 by a^3, you would simplify subtract.
So you would get a^-1. Make sense?

i only asked because i was goind to pick D as the one to cross off
