What is the square rout of 81

Learn how to spell dammit. It's root. Not rout.

I got that right cuz I KNOW IT ALL.

R

O

T

Not 9, positive OR negative 9

@Liv I know I hate it when people spell easy words wrong

Really, caterpillar? You insist on correcting the spelling and misspell it?

I have no idea what a 'square rout" is. I can tell you that the square root of 81 is 9, though.
