Square root symbol
About[]
A square root of a number is ...
... a value that can be multiplied by itself to give the original number.[1]
To help remember imagine the root of a tree:
"You know the tree, but what is the root that made it?"
"I know the tree, but what is the root that made it?"
In this case the tree is "9", and the root is "3".
