Question

Scrieti in baza 2 numerele:
2;13;55

Answer 1

2 : 2 = 1 rest 0

1: 2 = 0 rest 1

numarul 2 = 10

13: 2 = 6 rest 1

6 : 2 = 3 rest 0

3: 2 = 1 rest 1

1 : 2 = 0 rest 1

numarul 2 = 1101

55: 2 = 27 rest 1

27 : 2 = 13 rest 1

13: 2 = 6 rest 1

6 : 2 = 3 rest 0

3: 2 = 1 rest 1

1 : 2 = 0 rest 1

numarul 55 = 110111

Answer 2

2(10)=10(2)=2^1 +0x2^0 =2(10), deci 10

13(10)= 2^3 + 2^2 + 2^0 = 8+4+1 =13 = 1x2^3 + 1x2^2 + 0x2^1 + 1 x 2^0 = 1101

55(10)= 32+16+4+2+1 = 1x2^5 + 1x2^4 + 0x2^3 + 1x2^2 + 1x2^1 + 1x2^0 = 110111
