When L'Hopital's Rule fails

  1. Sep 17, 2007 #1
    I'm suppose to find the limit as x goes to infinity of [(9x + 1) ^ (1/2)] / [(x+1) ^ (1/2)].

    L'Hopital's Rule does not work on here (it said so even in the directions) as the function keeps on cycling.

    ...they gave us the answer (3) but I need to find out how.

    :S

    Figured it out.
