dont think I am trying to get anyone to do my homework, I had around
250+ Prep questions to do and have done them all except for the few I
have posted on this newsgroup. I have also attempted to show my working
out.
Thanks For your Help
Nathan
Question 1
----------
3x^-2 =
Question 2
----------
(y-1)/(y^2-2)
Question 3
----------
2-a^2-2ay+a^3y
Question 4
----------
2-a^2-2ay+a^3y
My Working:
Is this correct?
((sqrt)2-a)((sqrt)2+a) + ay(2+a^2)
Question 5
----------
9c^20/9a-y^20

3x^-2 = 3 * (1/(x^2)) = 3/(x^2)
also of note
3x^(1/2) = 3 * sqrt(x)
