11.5^7/5^3=5^4. The answer key says 1/5^4.

16. Sorry, can’t copy and paste, and trying to write out fractions and exponents through just typing is confusing! I got 16a^8 b^4, but key says b^4/16a^8.

18. I got 64a^2 b. Key : 4/a^10 b^13.

22. Me: 5y^4 x^4/4. Key: 5x^4/4y^4.

23. Me: x^6 y^6. Key: x^6/y^6.

24. Me: 15a^3 b/4. Key: 15a^3/4b^7.

Hope this makes sense. And hopefully I did my calculations correctly!
