  1. Hey guys bumping on the highest integer with 3 digits.
    We start to get really big numbers. Wrote a little code and still ran out of digits,

    Google give us 1.9662705e+77 that is rather large.
    Using Octave we get very similar at
    octave:1> 9^9^9
    ans = 1.9663e+77

    9^9^9 = 387420489^9 = 1.9662705e+77

    It get to be enough digits my head hurts.

    If you have a clean way to calculate I would enjoy seeing more than my TI89 can handle I believe but you guys do a little magic with calculators so may you can make it work.

    Looks like summer is slowing you guys down.

  2. Reading through this I may still need to work on this since it looks like my answer is still wrong because in truth it should be 9^387420489 I guess summer is getting to me.

    Back to Octave, obviously I have nothing to do on a Saturday night.

  3. octave:27> 9^387420489
    ans = Inf

    octave:39> 10^(0.631570358743543095) * 10^369693099
    ans = Inf

    running over to
    seem like I was wrong originally and they are a little more precise but as close as they will give for free is below which is way more accurate than I can prove.
    9^387420489=4.281247731757470480369871159305635213390554822414435 * 10^369693099

    Which is way more accurate than I can prove is there a longhand version that some can show with logs? I can probably search for it as well. Trying to use tools and hard head first. But beyond my capabilities to do long hand.

  4. If you don’t have operators it is 999, if you do have operators then it is as big as the operator can become. For example if you make the operators 9!^9!^9! then it will be even bigger than the above answer but you can include even more operators to increase it more like ((((((((((999!)!)!)!)!)!)!)!)!)!) making it become extremely high but you could even create your own operator and do whatever you want with that ex: %* will make any 3 numbers turn into infinity. So then the answer would be %*999.

    • Hi T Man
      very thorough solutions, however the free app was already claimed by the first respondent.
      Stay tuned, new challenges are coming up soon.
