length of the length is 146 digits
A googol is

, and a googolplex is

What is
5
5
5
? With base 10 logarithms, the length of this enormous number can be calculated:
5
5
log
10
5=2184.281264...
. Rounding up the part before the decimal point gives the length as 2185 digits. Let the part after the decimal point be
a=.281264…
, then the digits of
a
10
give the start of the enormous number, 1911….
With modulus methods, the ends of huge numbers can also be calculated. This Demonstration uses both logs and modulus methods to give glimpses at enormous numbers bigger than a googolplex.
