Thanks to anyone who helps right away and need right answer from the people who have already taken this test.
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.
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)(1/(-2)^4 (4)^2
= (1/2)(1/16)(16) = 1/2
Oh thankyou . I'm sorry for changing my name . So I really just put m original name . I was thinking that you have to change your name in order to put in another question,. Thanks oh my real name is Evan . So that's what I'm going to put no on. Thank you. And did you do the test before with the same quetions ? If so can you give them all to me.
