comment Find the group of automorphisms of the Petersen graph
Standard drawings of the Petersen graph are highly symmetric. Use your visual intuition to list all the automorphisms (and then use your logical mind to make sure that's all of them).

comment How to prove if log is rational/irrational
Could you pin down a more specific question? "Advice on approaching thought construct to logs" is very broad and vague.

comment Create dynamic cities of perspective angle x
Why does a 75° angle limit how deep your buildings can be?

comment A Different Type of Knights and Knaves
This is exactly the same as the standard Knight/Knave puzzle involving two doors. The proposition "the left door is the correct one" is replaced by "someone has proven GC", that's all.

comment Check if questions can be assigned to students
So you need general conditions on $N, M, (A_i)_i$ such that the problem has a solution?

comment Hashing With Chaining Collision
Could you be a little more detailed about how the hashing works? The objects are numbers $1...1000$, the keys are numbers $0...9$, but what does "two keys map two elements to one index" mean?

comment Shortest path between two points via two disks
Do you really mean a point in the disk, or in the circle?

comment Finding a cubic polynomial whose splitting field over $\mathbb{Q}$ equals $\mathbb{Q}(a)$ if $a$ is any of its roots
What about $x^3-1$? Its splitting field is generated by a single root, but that doesn't quite fit your question because you have to be careful which root you choose.

comment Why is $0/0$ not $\Bbb R$?
What would it help to say it's equal to $\mathbb R$? What problems would be easier to solve or have more elegant solutions? What theorems would be simplified?

comment Which book is appropriate for a Chemistry student that needs to learn basics about integrals?
I think the wording "non-mathematical student" suggests something like an art or history student, so I took the liberty of editing your title.
