Integrate x^(4/x)

Integrate x^(4/x)

(no result found in terms of standard mathematical functions)

I have had a long look at this one - I think the integral is intractable.Which means you can't solve it algebraically.   Did this one crop up in a text book?

Thanks guests

I don't remember where it came from. I asked it once before, a very long time ago. I got no responses.

I saw it in my watchlist and I just thought I'd ask again. :)
