The number 1 with 25 zeros after it is called a septillion. In scientific notation, it is written as 1 x 10^25. This number represents a very large quantity, as each additional zero increases the value by a factor of 10.

How many zeros are in the number 1googolplex?

First, when dealing with powers of 10 the number of zeros in the number is equal to the power of the 10: 101 = 10 which has 1 zero 102 = 100 which has 2 zeros 103 = 1000 which has 3 zeros etc. A googolplex is 10googol A googlol is 10100 → a googolplex = 10(10100) → a googolplex has a googol, or 10100 (which is 1 followed by 100 zeros) zeros. ie a googolplex has 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 zeros


One and a Google zeros?

I assume you mean "How many zeros are in a googol?" Well, 1 googol = 10,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000 which is 100 zeros.

What if there are 20 zeros what is it called?

It's not called anything unless there's a digit before all the zeros. If there's a ' 1 ' before them, then it's one hundred quintillion.
