comment When is a number square in Galois field p^n if it's not square mod p?
Tough choice because the answers was very similar, but Bruno's answer did it a little better for me this time. But thank you too - I found your answer useful aswell :)

comment Solution check: integral calculation using transformations
I have $\sin^21$ as solution, but it's not clear to me how you solved this. Did you draw the area and find the integration limits? What were they? There is no wolframalpha-way to check if you don't have the limits...

comment Is it possible that “A counter-example exists but it cannot be found”
No, I don't. I already pointed out that I'd say you can only imagine a single number at once i.e. in a Planck time. However, if you want to make this precise, you have to use numbers that have been described and ask to provide a counter-example. It's not that hard to define a described number - $n$ is a described number iff such written or told description has ever existed that the natural number $n$ fits it and no other natural number fits it.

My bad, I agree with your result then :)

comment Evaluate $\iiint xyz$
@AméricoTavares I did not downvote but it seemed wrong. If we'd take shape where all coordinates are between 0 and 9 we can't get bigger than a cube with side length 9 which has a volume of 729.
