Well, first, I'm assuming that you are referring to "googolplex" and not "googleplex" as per your title (which actually refers the the internet Search Giant Google's Headquarters)
And to find out what a googolplex is, we first define a googol:
1 googol = 1 with 100 zeroes after it = 10 ^ 100
The history behind the naming of the googol came in 1938 when Edward Kasner wrote this number and showed it to his nine year old nephew Milton Sirotta, her response was, as the legend goes, "googol!", and thus the googol came into existence.
Now, what is a googolplex?
Well, 1 googolplex = 1 with a googol zeroes after it = 10 ^ (10 ^ 100)
That's a lot of zeroes!
A mathmatition's nephew came up with the term "Google" for googleplex
googleplex and one, googleplex and 2, etc.
A googleplex and one
A googleplex and one.
Googleplex was created in 1997.
A googleplex is a large number represented as 10 raised to the power of a googol (10^100). This number is much larger than the observable universe and is used in mathematics and physics to describe extremely large quantities.
A googleplex is bigger than a google.
a googleplex and one
Googleplex Googleplex
Googleplex + 1
Yes, Googleplex is a number but it is very long
None. Googleplex is a number, not a shape and so does not have any sides.
