The next exercise

[Michael Heerdegen]

Hello,

my exercise for today is something I stumbled across a few days ago but
that is very nice: Answer with only using Emacs (or maybe your school
knowledge?):

The first three decimal digits (from the left) of 1001^1000 - i.e. one
thousand and one to the one thousand's power,

  1001*1001*...*1001
  \________________/
          ^
     1000 factors

are of course:

 (a) 2 7 1, the first three digits of Euler's number e

 (b) 3 1 4, the first three digits of the mathematical constant pi

 (c) 1 0 0, or

 (d) none of these

What's your choice?  How would you solve this using Emacs (or maybe even
without)?


Michael.
