Gargoogol-plexed is equal to 1010200, or 10 to the power of gargoogol.[1][2] It is equal to 1 with 100 quinsexagintillion zeros, which is 10200+1 digits long.

When evaluating gargoogolplex, the -plex suffix is evaluated first, making the result the square of a googolplex. If the gar- prefix is evaluated first, the result is 10 to the power of googol-squared, which is a much larger number (it is equal to googolplex to the power of googol, while gargoogolplex is googolplex to the power of 2).

Username5243 calls this number gooducolplex, and it's equal to 10[1]10[1]200 in Username5243's Array Notation.[3]

Writing down the full decimal expansion would take 10194 books of 400 pages each, with 2,500 digits on each page.
