I can get as far as integral of sqrt(1+9x^4-(1/12x^4)) before running into substitution problems... what should I set U to be? I tried using x^4 but I keep getting screwed up somewhere.. Thanks in advance!

Thanks a lot! I got the answer, but I'm just curious as to how the -(1/2) appears when you square, and disappears again when you simplify... sorry I'm probably missing something obvious here haha
