Is googolplex longer than pi

Longer ? Do you mean "Which number has more digits in it ?"

If that's your question, then the answer is: 'pi' .

"googleplex" is a rational number. To write it, you write a ' 1 ', and then you write

1 google zeros after it, and you're done. The entire number is written down on paper.

But 'pi' is an irrational number. You can never write the entire number on paper,

no matter how many digits you write down. Even if you wrote two googleplex

digits, the number on your paper would be very close to the true value of 'pi'

but it could never be exact.

So 1 googleplex can end, but 'pi' can't. So 'pi' has more digits in it.

I really hope that was your question.
