Im not sure how to do this.

(5q^3)(-12q^-4n^4)

So far what i did was multiply 5 by -12 to get -60. Then q^3 by q^-4 to get q^-1. I don't know what to do after this. Maybe you could tell me what I should do and then I can solve it. I was taught exponent rules but I'm not quite sure about this.

My Final Answer:
-60q^-1n^4

Yes, that is it.

-60q-1n4
