Without using a calculator

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

What do you mean:
256TB=2^{48}B=281474976710656B

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

 

To me,it sounds like something really stupid...I don't know why i even bothered to answer...:yuck:

Daniel.

 

I tried just counting up to that number on my fingers and toes, alas I maxed out at 1,048,575. Right now, I have the population of Anchorage, AK working on the problem.

Oh, please, please hurry before too many fingers and toes fall off from frost bite

 

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

Daniel.

 

ToxicBug,

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 ?

 

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

Daniel.

 

2^48 without a calculator?
Wow, i must of been gone way to long. :uhh:

 

Any one can do it,provided he/she has a piece of papaer and a pencil,so let's not exaggerate...

Daniel.

 

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 ......... that is a lot of twos. I should be doing something else more productive right about now.

 

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

 

I second that.:)
