# googolplex

*googolplex* is $10^{{10^{{100}}}}$; that is, 10 raised to the googol-th power. This can also be viewed as a one followed by a googol of zeros at its right. A googoplex is much larger than a googol. In fact, since a googolplex has
a googol number of zeros in its decimal representation, a googoplex has more digits than there are atoms in our universe. Thus, even if all matter in the universe were at one’s disposal, it would not be possible to write down the decimal representation of a googolplex.

## Problem question re decimal representation of googoplex

I can see that following the rule 10^x can also be represented by 1 followed by x zeros, a googolplex can be represented by 1 followed by a googol zeros. But a googol zeros can be written out as 1 followed by 100 zeros,so why is a googolplex impossible to write out in decimal representation

It depends in what sense you mean "impossible". In a theoretical sense, of course one can write out a google zeros. In a practical sense, it is impossible since there isn't enough paper or ink or time available in our universe to carry out the task of writing that many zeros!
