i have a question tho, hw many people see the puzzle, solve it or look at the awncer then go away?

how many of them, if intrigued, bother to go to a second page?

I think reading the answers you all give is some of the best parts of this place. Y'all make me laugh when you argue.

Thats what I was thinkingWell, I tried the square-root operator, and it yielded an answer that was too big. So I figured, how about the third-root (Cube-root)? Still too big. So the fourth-root works, though. So putting the operator between the numbers would imply a multiplication operation, a two-in-one deal. The fourth-root of nine is approx. 1.372. Multiply that by five to get approx. 8.660, which is greater than five, and less than nine.

No, this would not actually work. It would translate to five times the square root of nine. Since the square root of nine is three, the value would then be fifteen, which is not less than nine.

what if u wrote it this way: 5[[9]]

[9]=square root of nine

[[9]]=fourth root of nine
