SUMMARY

The integral problem presented is \int e^{a\left[\left(\frac{x}{b}\right)^{\frac{1}{4}}-1\right]}dx, where a and b are constants. The solution can be simplified to e^{-a}\int e^{a\left(\frac{x}{b}\right)^{\frac{1}{4}}}dx, which further reduces to e^{-a}\int e^{cx^{\frac{1}{4}}}dx with c = a/b^{1/4}. This transformation makes the integral less intimidating and easier to approach for further evaluation.

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! :smile:

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?
