Miss sue did you notice the answer you gave me the person who did it didn't do it right because its to the negative 4 power thanks . Can you try to solve it on your own? Thanks if you do.

Thank you! I knew how to do it but I kept on second guessing myself
Oh Sam and me are the same person in this question.
Please try to stick with one name.
If you had looked carefully at the solution I gave you before, you would have noticed that I took care of the
a^-4 by converting it to 1/a^4
Here is what I did, look it over carefully
#7 , the way you typed it ... it would be
(1/2)a^-4 b^2
= (1/2)(1/(-2)^4 (4)^2
= (1/2)(1/16)(16) = 1/2
