Hi;
For 9^9^9^5 ( I leave out the bracketing from now on ) is a major undertaking and I used a
recurrence.
And you missed my point, post #18 does suggest another way.

I meant-do you have another method for evaluating those kinds of numbers in general, for example, less than 9^9^9^5?

This suggests another method but in this case it fails. As a matter of fact it fails for
9^(9^(9^9))) too! His number is just too large.

Do you know any?

Hi;
That is the only one that I use consistently. Of course there are other methods but they are all experimental.

Hi bobbym
Is there a way to get the front digits of a number other than the one you showed me in the big Oh thread?

Hi;
That is 92 in decimal. Your question boils down to this:
which means it is larger than my current limit of 9^(9^(9^5)). As a matter of fact
it is larger than 9^(9^(9^(9))) which I have struggled with for more than 10 years.

I'm back again! Is that 92 in hex?
I have an even bigger challenge for you, would you be so kind as to calculate 141!^(162!^164!) for me please? to as large an accuracy as you dare! (ridiculous, I know!)
Thanks,
Rob

Hi sulley and all;
I was not born in July. Records of my birth have been destroyed. Hospital burned down and so did the rectory.
Yes it would interest me, but realistically I will have very little use for the knowledge, so I won't take any more of your time.
Then it will die with me. It does appear I am 92 but no one believes that so sometimes I am younger.

I think so.

Is that reliable information though?

Well, he has given us some info about his age. He was born on the 3rd of July and on Sunday...

Or am I missing something.
Yes! bobbym regularly lies about his age.
As far as I know only three people know for sure, and two of those are doubtful.

There is a math way but it is a bit complicated if you have never seen it before.
Are you interested?
Yes it would interest me, but realistically I will have very little use for the knowledge, so I won't take any more of your time.

that's massive^massive. 10 or more years ago I went after the front digit of that number. I was a mere lad of only 82 years of age so I figured I would bring it to its knees before I died...
Doesn't that make you 92? Or am I missing something.
Thanks again for you help,
Rob

For the tower problem? I do not know which one it is.
