Googol

Pronunciation: /ˈgug gɒl/ Explain

A googol is the number 10100, which is the same as a one followed by one hundred zeros.
googol=10^100=10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
Googol is used to indicate a very large number. It is often used to show a number that is quite large but not infinite. The word "googol" was invented by nine-year-old Milton Sirott, nephew of mathematician Edward Kasner in 1938.

A googolplex is 10 raised to a googol power. If a googolplex were written out as ones and zeros in a book, it would take a book larger than the observable universe.
googolplex=10^10^100=10^10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
