OK I'm a bit stumped. Can anyone explain in as clear and plane terms as possible why 9 to the power of 1/2 = 3? (or more exactly why 9 to the power of 1/2 is equivalent to the square root of 9, which of course again is 3). I don't get it.

PS, sorry, I wish I knew how to use your formula editing script to write my formulas... It would make everything much easier to read.
