@Sophie The room is intended for bounties which already ended, and the user is still interested in the question (and willing to reward answerers if an answer fulfilling their requirements is posted). See the rules described here.
But I don't think that there is too much harm in posting it here a bit prematurely - if it gets no answer until tomorrow it will fulfill the criteria.

This is an attempt to generalize this question. $$x^n-2y^n=1\implies \frac{x}{y}=\left(2+\frac{1}{y^n}\right)^{\frac 1 n}=2^\frac1n\left(1+\frac{1}{2y^n}\right)^\frac1n<2^\frac 1n\left(1+\frac{1}{2ny^n}\right)$$ $$0<\frac{x}{y}-2^\frac1n<\frac{2^\frac1n}{2ny^n}$$ but since the irrationality meas...
Basically in this post on meta I suggested that we create some place for the bounties which already ended and the OP is still not satisfied with the answer (or did not get any answers). This room is an attempt to create such place.
The bounties which are still active receive additional attention because they are in the featured tab. And the plan is that from here also the past bounties question - which are no longer on that tab - could get some additional views and possibly, in some cases, also an answer.
