Let [tex]\mathbb{P}[/tex] the set of primes. Let's [tex]p,q \in \mathbb{P}[/tex] and [tex]p \le q.[/tex] Find the pairs [tex](p,q)[/tex] such that [tex]2^p+3^q[/tex] and [tex]2^q+3^p[/tex] are simultaneously primes.

Hi Borek,
I do not have a solution for this problem...
I found only four solutions: [tex](1,1), (1,2), (2,3), (2,6).[/tex]

Neither is 1 so only one of the 4 pairs posted is acceptable. There is still another very obvious pair that was overlooked.

Sorry... :blushing: I meant the sixth prime number.
In summary, then, the only solutions [tex](p,q)[/tex] that I found are [tex](2,2),(2,3),(3,5), (3,13).[/tex]
