Have you ever heard of a googolplex?

Yeah, isn't it a huge number?

It's actually 10 raised to the power of a googol, which is mind-blowing!

Root Explanation

Googolplex is formed from "googol" (a term coined by mathematician Edward Kasner in the early 20th century, representing the number 10 raised to the power of 100) and "plex" (from the Greek "plexis", meaning to fold or to weave). The term "googolplex" refers to a number that is 10 raised to the power of a googol, or 10^(10^100).

Memory Tip

Think of a 'googol' as a huge number and 'plex' as something that is 'folded' or 'expanded' — a googolplex is an unimaginably large number that expands beyond a googol.
