Question

determinati nr naturale care impartite la 50 dau ca rest patratului catului

Answer 1

a : 50 = c r ; r = c^2 ; r < 50
a = 50×c+c^2

ptr c = 7
a = 50×7 + 49 = 399

ptr c = 6
a = 50×6+36 = 336

ptr c = 5
a = 50×5+25 = 275

ptr c = 4
a = 50×4+16 = 216

ptr c = 3
a = 50×3+9 = 159

ptr c = 2
a = 50×2+4 = 104

ptr c = 1
a = 50×1+1 = 51

51 ; 104; 159; 216; 275; 336; 399 .
