I have to integrate:(adsbygoogle = window.adsbygoogle || []).push({});

sqrt( (3t^2)^2 + (1)^2 + (sqrt(6)t)^2 ) at the limits t=1 and t=3

I cant figure out how to simplify the problem so that I can do the integral.

So far the farthest I've gotten is the obvious:

sqrt( 9t^4 + 6t^2 + 1 )

now im stuck.
