Thread: Question with integration of a binomial series

Could someone please tell me if I am correct so far in my integration of this binomial series and then help me get it into summation notation?: Question: Evaluate: http://www.wolframalpha.com/input/?i=integral+of+sqrt(1%2Bx^4)+from+0 - Pastebin.com My work so far: http://f.imgtmp.com/Flmt3.jpg

Any help would be greatly appreciated!
Thanks in advance!

I found a mistake. 5/96 should be replaced by 1/64 but I still can't find the pattern to make the part before the final answer to be the final answer with the summation form.
