The square root of any negative number is equal to the square root of its absolute value followed by i - an imaginary number representing the square root of minus one. Therefore, such that sqrt(25) = 5, sqrt(-25) = 5i.
Negative square root is -√Square root of negative one is i.
Such that the square root of 363 is equal to 19.05256 (rounded to five decimal places), the square root of -363 is euqal to 19.05256 i. The lower-case letter i represents the square root of minus one, an imaginary number.
To take the square root of any power, just reduce the exponent to one-half of each value.
The square root of any negative number will always be a complex number. The word 'complex' can be supplemented for the word 'imaginary' which is what they can sometimes be called. 'i' stands for imaginary and equals the square root of minus one. sq(-1) = i - (that is the basic fact) The imaginary numbers work in a quadratic fashion (x^2) so: sq(-1) = i sq(-4) = 2i sq(-9) = 3i (so it takes the positive form of the number and square roots it, then multiplies it by i) Example: sq(-2) = sq(2)x (i) = (1.4142 x i) = 1.4142i

Four of anything minus one of the same thing always leaves three of them.
It is +1
The square root of negative one is an imaginary number, signified by the italic lower-case i.
The square root of any negative number is equal to the square root of its absolute value followed by i - an imaginary number representing the square root of minus one. Therefore, such that sqrt(25) = 5, sqrt(-25) = 5i.
[ 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.
It has to be a stupid answer anyway
X= plus or minus 1
