Clever. I initially thought of this 5 > 9, but there's not really a number there. 5 > x > 9 would be more appropriate I guess.

me too. man i thought i had it.

Well, 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.

I agree with you

You could also put a square root sign between them

No, because putting a square root between them would mean:
5 "times" the square root of nine, or 5x3, which is 15.
and 15 is not smaller than nine...but it was a nice try!

I agree with you

great thinking!
that means there is an infinite solution set:
5 nth root 9, where n>3

One could also insert an arctan between the 5 and 9. This would give you 5*arctan(9) = 5*(1.46) = 7.3 which is between 5 and 9.
