#20. -2a cubed over 10a to the eighth power.
-----
Maybe you know the exponent tells you the number of the base factor.
Your problem could be written as follows;
= [-2aaa]/[10aaaaaaaa]

Cancel common factors to get the answer.
===========================================

#22. x cubed times y to the zero power times x to the negative 7th power.
[xxx*y*z^0][x^-7]
---
The negative on the exponent means "invert".
z^0 = 1
----
So you have:
= [xxx*y*1][1(xxxxxxx)]
---
Cancel common factors to get the answer.
