Steve,
sounds like you need some good solid inperson help. Or, to move matters along, tell us where you get stuck. You must have some idea how to get started on these problems.
If not, and here it is the end of the semester, you really do need some personal help. Also, there is a ton of help online, at all levels. If you do a google search on something as crazy as
algebra how do exponents work
or
algebra why do we add exponents when we multiply powers
you'll get lots of elementary help.
