## The Attempt at a Solution

I'm having a horrible time trying to do it. Problem is, I don't know how to start. The only thing I can think of is using trigonometric substitution. But I don't know how to manipulate the function in order to make it fit. A hint would be greatly appreciated.

*Edit* I made a mistake, it's

∫√(((x)^4)/2 + 9) dx I accidentally put it to the 2nd power instead to the 4th...
