How do we convert decimal numbers into binary numbers 2483?.
alisha [4.7K]

Answer:

Places in binary coding

1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 - 2048

2483 - 2048 = 435      there is 1 in the 2048 position

435 - 256 = 179    there is 1 in the 256 position

179 - 128 = 51        there is 1 in the 128 position

51 - 32 = 19         there is 1 in the 32 position

19 - 16 = 3           there is 1 in the 16 position

3 - 2 = 1            there is 1 in the 2 position

1 - 1 = 0             there is 1 in the 1 position

10011011 0011     would be the binary result

Check:

2048 + 0 + 0 + 256 + 128 + 0 + 32 + 16 + 0 + 0 + 2 + 1 = 2483

Stells [14]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
2^n - 3 = 83 
<span>2^n = 86 </span>
<span>ln(2^n) = ln(86) </span>
<span>n*ln(2) = ln(86) </span>
<span>n= ln(86)/[ln(2)] (which is the same as "log base 2 of 86") </span>
<span>n= 6.426264755</span>
