Formal target: Corpus.Mathoverflow17560.mathoverflow_17560
If $2^x$ and $3^x$ are integers, then $x$ must be an integer.
Exact formal statement
∀ {x : Real},
(Exists.{1} fun m => Eq.{1} (HPow.hPow.{0, 0, 0} 2 x) (Nat.cast.{0} m)) →
(Exists.{1} fun m => Eq.{1} (HPow.hPow.{0, 0, 0} 3 x) (Nat.cast.{0} m)) →
Exists.{1} fun m => Eq.{1} x (Nat.cast.{0} m)This target is a formal statement, not a proof of the problem.
