Im joking, dtewi. Heres why its wrong:
The square root of a number elevated to square (again, not sure on english) is the module of that number. So:
(4 - (9/2))2 = (5 - (9/2))2
You cant just remove the square and eliminate the 9/2. Actually is this:
!4 - (9/2)! = !5 - (9/2)! (! stands for the module)
!-0,5! = !0,5!
0,5 = 0,5
See?

Oh, that was to the power of two?
The notation for "to the power of" is ^.

All you had to do was watch how thw 81/4 turned into 9/2. What do you thing happened?
But I still say 0.9999 is different than 1.
Know why?
Cause 0.999999 has no 1 in it.
