Question

aflati divizori lui 32 si determinati numerele naturale xstiind ca 32 :(2×x+4) ​

Answer 1

D (32) = 1, 2, 4, 8, 16, 32

32 : (2 x X + 4) => 2 x X + 4 = 1, 2, 4, 8, 16 sau 32  

2 x X = 1 - 4 nu convine, 2-4 nu convine, 4 - 4, 8 - 4, 16 - 4, 32 - 4

= 0, 4, 12, 28

X = 0 : 2 nu convine, 4 : 2, 12 : 2, 28 : 2

= 2, 6, 14

32 : (2 x X + 4) => 32 : 2, 6 nu convine, 14 nu convine

=> X = 8 deoarece (2 x 2) + 4 = 8

E ok?
