Bonjour,

Le 09/07/2023 10:37, Michel Talon répondait à robby :

Bon, ça m'étonnerait que ce soit vraiment une réponse à la question de robby.
Du coup tu aurais mieux fait de répondre à l'article de Richard.

>>> (a^b)-(b^a)=17

> (%i4) for x from 1 thru 50 do for y from 1 thru 50 do if x^y-y^x=17 then 
> print(x,y);
> 
> 3 4
> 18 1

Pourquoi avoir éliminé à priori les valeurs négatives et les valeurs
non-entières ? Tu as une preuve qu'aucune d'entre elles ne peut convenir ?
