Evan,
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.

Oh Sam and me are the same person in this question.

Sam or Dave or Evan  Algebra 1 I need help!!!!!!!!!!!!!!!! 
Reiny,
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
