Perfecta

#4850

O matrice cu n linii şi m coloane se completează aleatoriu cu numerele \( 2^{1}, 2^{2},…, 2^{n\cdot m}\), fiecare număr fiind folosit o singură dată. Matricea se numeşte perfecta dacă produsul elementelor pe fiecare linie şi fiecare coloană este pătrat perfect. Să se afle câte matrice perfecte se pot forma.
