Question

1. Calculează: a) 54 (10) = (2) b) 110101 (2) = (10)

Exercitiu 1 va rog​

Answer 1

Explicație pas cu pas:

54:2 = 27 rest 0

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

$\bf 54_{10} = 110110_{2}$

.

$110101_{2} = 1 \cdot 2^{5} + 1 \cdot 2^{4} + 0 \cdot 2^{3} + 1 \cdot 2^{2} + 0 \cdot 2^{1} + 1 \cdot 2^{0} =$

$= 32 + 16 + 4 + 1 = \bf 53_{10}$
