Four of anything minus one of the same thing always leaves three of them.
It is +1
[ 2 minus square root of 5 ] is the only one.
Rounded to two decimal places, sqrt(-2272) = 47.67 i. i is an imaginary number equal to the square root of minus one, and thus 47.67 i is equal to 47.67 times the square root of minus 1.
It has to be a stupid answer anyway

There is no real answer. The square root of negative one is denoted i for imaginary.

[ 2 minus square root of 5 ] is the only one.
Negative square root is -√Square root of negative one is i.
Rounded to two decimal places, sqrt(-2272) = 47.67 i. i is an imaginary number equal to the square root of minus one, and thus 47.67 i is equal to 47.67 times the square root of minus 1.
I, the square root of -1
If this is supposed to be a riddle, it's not a very good one. The square root of the number whose square root is two is, obviously, two.

X= plus or minus 1
This one's ugly.(5 times the square root of 23 minus 4it)(5 times the square root of 23 plus 4it)where i is the square root of negative one.
