comment How to solve equations to the fourth power?
@imulsion Here is a more sophisticated question of similar quality with 1/3 the upvotes (currently). This one is nearly a duplicate with 1/5 the upvotes. The vagaries of SE voting are renowned. (I do agree, however, that the AlecTeal's tone appears rude, and I think the argument that the question should be downvoted, implied IMO by the assertion that it is "not well researched," is off-base for the reason you cite.)

@user85361 The OP is referring to his six-year old child. It's colloquial in English.

comment differntial geometry
This site is for question about the software program called Mathematica (see mathematica.stackexchange.com/help/on-topic). This seems to be a question about mathematics. Is that right?

comment Is it possible to find $n$ from the sum forming a polynomial?
Yes, just what I was thinking. Kind of a strange problem.

comment Is it possible to find $n$ from the sum forming a polynomial?
@Nasser I suppose one ought to point out that the computation shows that there is, in fact, no solution.

comment Derivation: How do I derivate this
Perhaps FullSimplify[SeriesCoefficient[Exp[-y^2], {y, x, n}] n!, Element[n, Integers] && n > 0] (from V. Reshetnikov) or D[F[n][x] Exp[-x^2], x] // Factor is a better hint. But your question seems to be about mathematics, not the technical software Mathematica

comment Notation for sum of products
Is this a question about standard mathematical notation or about how to write code in the software system Mathematica to represent such a sum?
