I request you to please send me the step-by-step solution for the below theorem... Needed to be solved clearly, please... Needed a brief explanation...

Theorem (Hurwitz, 1891). Let a be irrational. Then there are infinitely many distinct rational numbers 2 for which V593 Proof. This needs more advanced number theory. (But proving that this inequality is strict, i.e., that v5 cannot be increased, would be hard but feasible. )
