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 http://octave-online.net/
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 WolframAlpha.com
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.
