The square root of negative one is an imaginary number, signified by the italic lower-case i.
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.
Four of anything minus one of the same thing always leaves three of them.

Negative square root is -√Square root of negative one is i.
I, the square root of -1

X= plus or minus 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.
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.
