I'm starting to get the hang of exponent laws and such, but I'm not quite sure if my answers are correct.
If anyone could take the time to walk me through the first one, and verify the other two, I'd really appreciate it (:

(z^6z^2z^-11)^4 ÷ z^-13

-28a^6b^-3c^5 ÷ 7a^11b^-5c^5
= -4a^-5b^2

(-2ab^7)^3 ÷ (- a^4b^2)^5
= 8a^-17b^11
