comment Blue eyes: a logic puzzle
@Keinstein, It is true that the islanders know both of those things. But those two facts alone are not sufficient to qualify as common knowledge. They need to know: "1) there are blue eyed people on the island. 2) Everyone is aware of fact 1. 3) Everyone is aware of fact 2. 4) Everyone is aware of fact 3... X) everyone is aware of fact X-1." for an X of any size. Prior to the guru's statement, each islander only knows facts 1 through N, which falls infinitely short of qualifying as common knowledge.

comment Prove that if $x^n = y^n$ and $n$ is even, then $x = y$ or $x = -y$
Does this assume a nonzero n? Otherwise, you can disprove it by showing that 1^0 = 2^0. Or is the question asking you to "prove that if x^n = y^n for all even n..."?

comment Change outcome of equation with variable that affects other variable
What do 8250 and 65536 represent in the formula? Are you willing to change one or both of them?
