How do you calculate the number of digits in the product of something like

4^187500000

?

No.  I'm just wondering if I have to reserve gigs or megabytes for the result.  o.0

There probably is.  I haven't learned it, though.  :(  If you find out, let me know, I'd be interested.

Log(4)*187500000=112,886,248.374


So I'm looking at 107.7MB of digits.  Not too bad!

Except I want to raise that result to the 16th power.  For a total of 4^3000000000 which represents the total number of possible combinations of DNA in the human genome.  

And that's 1.6GB of digits.  I'm not sure I have enough to ram to calculate that one out.  I'd have to write a specialized program to write the intermediate results to the disk.  :(

i knew he was missing a zero.

you want to calculate the possible combinations of the human genome on your home computer?
