I've understood a good portion of the test myself, but there's still quite a few that I need answers on...if you could help me, even on just a few, It will be so, so appreciated. Help...?

For 9-15, find the simplified form of each expression.

9. (k^-2)^9
k^18
1/k^512
1/k^18
k/18

10. (-h^4)^5
-h^9
h^1
h^20
-h^20

13. (6q^6)^-4
6q^1,296
1,296q^2
1/1,296q^24
6q^-24

14. (t^4/10y^4)^-4
10t^16y^16
10,000y^16/t^16
-40t^16/4y^16
10,000t^16/10y

15. (x^3/2y^6)^-3
x^9/-8y^18
8y^18/x^9
6y^9/x^6
x^6/-6y^9
