### singular

I have an integral in a physics problem that I can't solve. How would I go about solving the following:
$$\int e^{a\left[\left(\frac{x}{b}\right)^{\frac{1}{4}}-1\right]}dx$$
where a and b are constants

Hi singular!

You can make it look slightly less intimidating:
$$\int e^{a\left[\left(\frac{x}{b}\right)^{\frac{1}{4}}-1\right]}dx\,=\,e^{-a}\int e^{a\left(\frac{x}{b}\right)^{\frac{1}{4}}\,=\,\LARGE e^{-a}\int e^{cx^{\frac{1}{4}}}\,,$$
where c = a/b^1/4.

Does that help?
