What makes you think that there is a "nice" answer to this integral?

Or better yet, where did you find this integral?

What makes them "beautiful"? They all appear to be randomly constructed.

It's easy to see that Question 1 has a closed form via a simple substitution of y=x^pi + 7, but that doesn't make the integral beautiful.

@Pi Han Goh I don't find that reason good enough to undermine their beauty.
