PI poate fi: 16, 25, 36, 49, 64, 81 (patrate perfecte).
Dintre aceste numere, decat la 16, 25 si 36 putem adauga o alta cifra pentru a obtine un patrat perfect, adica 169, 256 si 361.
In primul caz avem PI=16 (adica 4*4) si E=9, si intr-adevar sqrt(PIE) = 13.
In celelalte 2 cazuri nu se obtine egalitatea.
Deci solutia este: P=1, I=6, E=9.
