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

What is an irrational number less than 0?
Oh, dude, an irrational number less than 0? That's like asking for a vegan steak - it just doesn't exist in the real world! Irrational numbers are those funky ones that can't be expressed as a simple fraction, and they can be positive or negative, but they're always a bit wild and unpredictable. So, yeah, there's no such thing as an irrational number less than 0.
