pai dac * inseamna inmultire:
13*13=169
365-169=196
√196=14
deci 365=13*13+14*14

365=13²+xy
365=169+xy
xy=365-169
xy=196
x=1=>y=196
x=2=>y=98
x=4=>y=49
x=14=>y=14
x=196=>y=1
x=98=>y=2
x=49=>y=4
=> x,y apartine (1,196);(2,98);(4,49);(14,14);(49,4);(98,2);(196,1)
daca cere suma de doua pătrate perfecte,atunci iei varianta (14,14)
