Question

Determinati numerele naturale prime a si b, daca 3a+5b=46

Answer 1

a=5+3+46=8+46=54
b=56-46=10

Answer 2

Numerele prime pana la 46 sunt: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43

Numerele a si b prime din sirul dat care indeplinesc conditia sunt a = 2  si b = 8

verificare:

3a + 5b = 46⇒ 3×2 + 5×8 = 46⇒ 6 + 40 = 46
