5 5. I couldn't even begin to … Source(s): Master's Degree in Math. googol = 10^100. A googolplex has a googol zeros. However in this "Googolplex Written Out" multivolume set of books, I am doing just that. In the table below, the first column lists the name of the number, the second provides the number of zeros that follow the initial digit, and the third tells you how many groups of three zeros you would need to write out each number. Anyway, a googol is 10^100, so it has 100 zeroes. I know what a googolplex is, its 10^10^100, or 10^googol. So the answer is: a googol of them. In other words, the number of zeros is: 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 (Remember, that's the number of zeros, not the number itself. That is a lot of zeros!, starting with a 10, and after that, there would be hundreds of zeros, thousands of zeros, even millions of zeros, like shown above. It helps track these multiples of 10 because the larger the number is, the more zeroes are needed. Beyond that is the googolplex, which is a one followed by a googol zeros. and I know how many zeros are in a googol, its one with a hundred zeros. 1 decade ago. NO, a googolplex is 10 to the 10th to the 100th. A googol has 100 zeros. I've even written it out before, it wasn't that hard, but ti did take a while. Al. A googol has 100 zeros. The much larger number googolplex has been defined as 1 followed by a googol zeros. googolplex = 10^(10^100) Answer: A googol zeros. But I want to be the first person (and hopefully the last) to actually write down the whole googolplex. A googolplex is actually a useless number to the scientific community because it exceeds the number of particles in the universe. [and so it was decided that googolplex should be] a specific finite number, with so many zeros after the 1 that the number of zeros is a googol. There are lots and lots of zeros in the Googolplexian. A googolplex is defined as the number that can be written as "1" followed by a googol of zeroes. A googolplex has a googol of zero No, a googolplex has 10 x 100 googols. And that's a lot. While this number can easily be written as googolplex = 10 googol = 10(10 100) using the exponential notation, it has often been claimed that the number googolplex is so large that it can never be written out in full. There isn't even enough surface area on the entire planet earth to write it out, even if you made each "0" the size of an atom!
