Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying find this integral:

[tex]

\int \frac{dx}{\sqrt{x} \left(1+x^2\right)}

[/tex]

I tried the substitution [itex]t = \sqrt{x}[/itex] and I got

[tex]

2 \int \frac{dt}{1+t^4}

[/tex]

which I'm not able to solve. I know it should be some simple substitution, but I can't see any...

Thank you for any help.
