I'm sorry to hear that neither your book nor your instructor covered this material before you were assigned homework on it. :shock:

Unfortunately, since the assignment is using non-standard terminology, we can't even know where to send you for lessons, to make up for what isn't being provided by your school. Please consider having a serious talk with your academic advisor or your school's administration.

Good luck! :D
 
i would bet it is asking you to make the exponents positive. i have guessed this based on this:
in both problems, the exponents are negetive.
both problems are not simplified.
so i fully simplified them:
1.)
(8a[sup:2jbsf79k]-5[/sup:2jbsf79k])[sup:2jbsf79k]2[/sup:2jbsf79k]=

8[sup:2jbsf79k]2[/sup:2jbsf79k]
----
a[sup:2jbsf79k]10[/sup:2jbsf79k]

64
----
a[sup:2jbsf79k]10[/sup:2jbsf79k]

2.)
1
----- =
(4b[sup:2jbsf79k]-6[/sup:2jbsf79k])[sup:2jbsf79k]2[/sup:2jbsf79k]

b[sup:2jbsf79k]12[/sup:2jbsf79k]
-----
4[sup:2jbsf79k]2[/sup:2jbsf79k]

b[sup:2jbsf79k]12[/sup:2jbsf79k]
-----
16

thats what i would do...
