Can you give the EXACT number of bytes there are in 256 terabytes? If you can, show how you did it.

10000000000 0000000000 0000000000 0000000000 00000000 (in binary) since it is 1024 x 1024 x 1024 x 1024 x 256

1TB=2^{40}B;256TB=2^{48}B=2^{51}b=2Pb

You have to give it in decimals, not in binary otherwise its too easy. Daniel your answer is wrong.

What do you mean:

256TB=2^{48}B=281474976710656B

Daniel.

256TB=2^{48}B=281474976710656B

This sounds sort of like a homework problem. "If you can, show how you did it," said ToxicBug.

Its a lot easier than that.

You take 2^X,Y where X is the units, for example: 0 - bytes, 1 - kilobytes, 4 - terabytes, etc. Then for Y you find the exponent 2^Y for the number. 256 is 2^8, so the answer is 2^48.

And why wasn't my answer right...?BTW,on both posts it coincides with yours...

Exponent notation is not a trick, it's a very normal tool used by almost all mathematicians, engineers, and physicists.

And how is this a decimal representation ?ToxicBug said:You take 2^X,Y where X is the units, for example: 0 - bytes, 1 - kilobytes, 4 - terabytes, etc. Then for Y you find the exponent 2^Y for the number. 256 is 2^8, so the answer is 2^48.

Good point...He probably meant the 15 digit number...BTW,it's called "BASE 10".

2^48 without a calculator?

Wow, i must of been gone way to long. :uhh:

You would square 1024, square the result, then multiply that by 128.
