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.

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).

Here it is: 428124773175747048036987115931...

Maxima can do it offhand and so can Alpha!

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