Sep 21, 2019 at 14:52 comment added user142929 Many thanks @user100927 I hope that this type of diophantine equations will be interesting for more mathematicians in the future. Many thanks again for your remark, and to the user who posted an answer for previous Question 1 and Question 2
Sep 20, 2019 at 13:23 comment added user100927 The questions reminds me of $a^b=b^a$ where the only nontrivial integer solution is $(a,b)=(2,4) or (4,2)$. However there one can show that b must divide a (or vice versa) and something similar does not work in your case.
