is the answer a negative or positive

18AB^5C^3/12B^2C

I come up with the answer of 3AB^3C^2/2 The instructor says the answer is correct but should be a negative. I don't understand how. Someone please help me. Thanks

Did you write the expression down correctly? If not, you may have forgotten that negative. The answer for what you have written would be what you have. There is no negative in the problem, therefore no negative in your answer. Good luck! :clap:

Unless there is a "minus" sign that you omitted in the original exercise, I don't see how you'd end up with a "minus" sign on the final answer. :shock:
