Count the number of zeros in the above number. Suppose that number is n. If n is even, then the answer is ±1 followed by n/2 zeros. If n is odd, then it is ±3.1623 followed by (n-1)/2 zeros, approx.


Is there any number bigger than Google?

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.


Google number represented as a one followed by 48 zeros in the UK?

No. 1. There is no such thing as a Google number. 2. Googol is a number represented as 1 followed by 100 zeros whereever it is used.


How do you write 7 trillion 2 million 31 thousand all together in a number?

To write 7 trillion 2 million 31 thousand as a single number, you need to add up the values of each part. 7 trillion is 7,000,000,000,000 (7 followed by 12 zeros), 2 million is 2,000,000 (2 followed by 6 zeros), and 31 thousand is 31,000 (31 followed by 3 zeros). Adding these together, you get 7,002,031,000,000.

How many zeros in a half of a billion?

THE ANSWER: 8. The number thats half of a billion is 500,000,000. It has 8 0's and 500,000,000x2=1,000,000,000,000.the "bi-" prefix implies 2;In countries that use the long scale (based on powers of a million) like Europe:1 billion = (106)2 = 1012 = 1 followed by 12 zeros = 10 followed by 11 zeros1/2 of this would be 5 followed by 11 zerosie eleven.In countries that use the short scale (based on powers of a thousand plus one) like USA:1 billion = (103)2+1 = 109 = 1 followed by 9 zeros = 10 followed by 8 zeros1/2 of this would be 5 followed by 8 zerosie eight.

How can patterns be used to determine products of a number and a power of 10?

2 X 104 is a 2 followed by four zeros. 5 x 109 is a 5 followed by nine zeros. 1 x 100 is a 1 followed by no zeros (1). When you multiply any number by 10n, you move the decimal point n places to the right. 8,000 x 103 = 8,000,000. So when you divide by a power of ten, you just move the decimal point to the left. Multiplying by 10n is the same as dividing by 10-n, and vice versa.
