Hmm,

Do you have a hint?

Say:

10^x=9^9^9

Take the common log of both sides.

Can you finish now?

That will help you get the number of digits in 9^9^9. But, gAr has already done that

Nope, that will get you the front digits.

Does the answer start with 428... ?

I think anonymnistefy has taken the log on e that is why he is getting it wrong

Yes, you need to take the common log else you can not get x by itself!

Ah, that's true. I forgot Log[x] was ln(x).

Maxima can do it offhand and so can Alpha!

Have you just tried entering it as a floating point number?

I do not know how to do anything with Maxima at all except to look at the manual and call functions
