Having some difficult with a few problems

if you could explain how to do the equation that would be great!

1)

the answer has to be in the form of f(x)/g(x)

2) After fully simplifying the expression

3)Simplify the complex rational expression
into a standard rational expression.

4)

solve for a and b

5)

use the rules and .

6)Evaluate the expression using .

I got 264 for this one...but we are allowed to check out work..and it says im wrong?

7)
If you rationalize the denominator of
then you will get

solve for r,x,n

Thanks for any help!
