I'm actually in 7th grade, but I'm doing 8th grade pre-algebra, but anyway, here:
I'm supposed to simplify these four problems and I don't really understand how:

28s (15 power)
____
42s (12 power)

4m+(n[7th power]m)

63m(5 power)n(6 power)
______________________
27mn

3a·4a(4 power)
______________
28a(2 power)
