  1. Sep 1, 2008 #1
    I hit the submit instead of the preview. please wait
    1. The problem statement, all variables and given/known data
    [tex]\int9s9^s ds[/tex]

    2. Relevant equations

    3. The attempt at a solution

    dv=9^s ds
    =∫3^(2s) ds
    this is as far as i have gotten. Am i correct so far?

    Yes, that is correct. You didn't really need to reduce to 3, that is exactly the same as
    [tex]\int 9^s ds= 9^s/ln(9)[/tex]
