Question

cine mă poate ajuta doar 7,8 dau coroana repede va rogg​ plizzzzz

Answer 1

Explicație pas cu pas:

121:2 = 60 rest 1

60:2 = 30 rest 0

30:2 = 15 rest 0

15:2 = 7 rest 1

7:2 = 3 rest 1

3:2 = 1 rest 1

1:2 = 0 rest 1

$\bf 125_{10} = 1111001_{2} \implies x = 1111001$

34:2 = 17 rest 0

17:2 = 8 rest 1

8:2 = 4 rest 0

4:2 = 2 rest 0

2:2 = 1 rest 0

1:2 = 0 rest 1

$\bf 34_{10} = 100010_{2} \implies x = 100010$

$11011_{2} = 1 \cdot 2^{4} + 1 \cdot 2^{3} + 0 \cdot 2^{2} + 1 \cdot 2^{1} + 1 \cdot 2^{0} = 16 + 8 + 0 + 2 + 1 = 27_{10}$

$\bf 11011_{2} = 27_{10} \implies \bf x = 27$

$101011_{2} = 1 \cdot 2^{5} + 0 \cdot 2^{4} + 1 \cdot 2^{3} + 0 \cdot 2^{2} + 1 \cdot 2^{1} + 1 \cdot 2^{0} = 32 + 8 + 0 + 2 + 1 = 43_{10}$

$\bf 101011_{2} = 43_{10} \implies x = 43$
