I believe you have the number of zeroes wrong. But starting with "billion", there are two different definitions, sometimes called the "short scale" and the "long scale". This is one of the reasons that it is preferable to use scientific notation, to avoid this ambiguity.
10 followed by nine zeros: 10,000,000,000
10 followed by 5 zeros is 1,000,000 (one million). 100 followed by 3 zeros is 100,000 (one hundred thousand) so 10 followed by 5 zeros is greater.
7500 followed by 9 zeros; that is 75 followed by 11 zeros in all
1 followed by 18 zeros is a quintillion.
This is one case where you can be told to Google it ... because the answer is Google.
1 with 57 zeros
10 followed by nine zeros: 10,000,000,000
No, but a googol (after which the search engine Google was named as a pun) does - a googol is 10100 which is a one followed by 100 zeros.
Google isn't a number. The search engine Google used that name as it is a pun on Googol which is a number, and is 10¹⁰⁰ which is a 1 followed by 100 zeros 10¹⁰⁰ + 1 (a 1 followed by 99 zeros followed by another 1), 10¹⁰⁰ + 2 (a 1 followed by 99 zeros followed by a 2), 10¹⁰⁰ + 3 (a 1 followed by 99 zeros followed by a 3), ... are bigger than a googol, so yes, there are numbers bigger than a googol. A googolplex is 10^googol = 10^(10¹⁰⁰) = 10^(100...0) where there are 100 zeros in the power of the 10; it is a 1 followed by a googol (ie 10¹⁰⁰) zeros. In fact there are infinitely many numbers greater than a googol as the counting numbers (1, 2, 3, ...) can each be added to a googol, and there are infinitely many counting numbers.
If you mean the number google, then it is a 1 followed by 100 zeros.
in my agenda at school, there is a little fact that the number centrillion, has 500 zeros. but, there is probaby a higher number out there. a googol is 1 followed by 100 zeros, but higher named number is a googolplex which is one followed by googol number of zeros - that's a lot of zeros!
In English-speeking countries, that would usually be a 1, followed by 12 zeros. In some other countries it's a 1, followed by 18 zeros.
10 followed by 5 zeros is 1,000,000 (one million). 100 followed by 3 zeros is 100,000 (one hundred thousand) so 10 followed by 5 zeros is greater.

Googolplexian: The worlds largest number with a name. A "1" followed by a googolplex of zeros Googolplex: The second largest number with a name. A "1" followed by a googol of zeros Googol: A large number. A "1" followed by one hundred zeros. There are infinitely many numbers, so there is no longest number.
1 followed by 18 zeros is a quintillion.
