    You don't normally use scientific calculators ? We've used them since grade 10 (I think, might have been 9).
    Can yours handle numbers in that size though? My can only get to 10^100-1 and I've seen up to 10^1000-1 but not larger.

    Never known about the science calculator in Windows either.
    We are all aware that the senses can be deceived, the eyes fooled. But how can we be sure our senses are not being deceived at any particular time, or even all the time? Might I just be a brain in a tank somewhere, tricked all my life into believing in the events of this world by some insane computer? And does my life gain or lose meaning based on my reaction to such solipsism?

    2^10000= 10^(lg2*10000)= 10^3010.2999566398119521373889472449
    If your teacher doesn't like that answer

    pick up the decimals of lg2*10000=3010.x

    so you get 10^0.x = 1.9950631168807583848837421626836

    Thus you get 1.9950631168807583848837421626836*10^3010

    Haven't anyone here learned to count with logaritmes?
    This is a better method, because it will work with any number, whereas my suggestion only works with powers of 2.

    And now I feel the effects of not having taken a math class in the last five years. When I was taking AP Calc I was on top of the world; now the good Duke's post is complete gibberish to me.
    And I have not done a maths course for 23 years. Is there a smug smiley?
    We all learn from experience. Unfortunately we don't all learn as much as we should.

    Better yet, take the integral of f(x) = x^2 for the interval [0, 2^10000].

    What does your calculator say about that?

    It says 2,646967839710986774710839276339*10^9030
    And I was using my own calculator not the windows version (except to get all the decimals in the end, can "only" get 10 on my own calc).

    BTW the windows calculator can handle numbers up to something in between 10^43429 and 10^43430.
    If 10^3010 is insanely big, what's 10^43429 then?

    Wow. That is a big number. My calc (A high-end 3d graphing calculator) will only do powers of 2 up to 3321.9280948873999999. Trying to do 2 to the power of 3321.9280948874 will give me infinity.
