simplify 12b^-6/3a^0 you should read my notes on "rob"'s questions if you're not the same person. lol if that's 12(b^-6), then the answer is 12/(b^6) if that's (12b)^-6, then the answer is 1/((12^6)*(b^6)) 12b^-6/3a^0. I think this is 12(b^-6)/3(a^0). a^0

In school we're learning to use the quadratic formula. I understand how to use it and what its applications are, but I don't understand why sometime it's okay to simplify and sometimes it's not. For example, I got the result (-2 ± 2 square root of 6)/2.
