Answer:

-4arccos(x^(1/4)) +C

Explanation:

My machine solver gives an answer that reduces to the expression ...

-4arccos(x^(1/4)) +C

__

We know that ...

(d/dx)arccos(x) = -1/√(1-x²)

If you let u = x^(1/4), then you can make the integrand look something like ...

4 du/√(1 -u²)

which is what you need to get to the arccos function.
