Answer 1

___

xyz

xy + y z + z x = 66

x + y + z = 6;   iar x, y, z ≠ 0 ( diferite de 0 )

xyz= 114;  141;  123;  132;  213;  231;   312;   321;   411 → numerele de ordinul 3

Verific:

xyz = 114;  xy + yz +zx = 11 + 14 + 41 = 66

xyz = 141;  xy + yz +zx = 14 + 41 + 11 = 66

xyz = 123;   xy + yz +zx = 12 + 23 + 31 = 66

xyz = 132;   xy + yz +zx = 13 + 32 + 21 = 66
