What is an unreal in math?
The only thing I can think of that you might mean is an imaginary or complex number. Since there is no solution to √(-1) mathematicians labeled it as i which is the imaginary number, and any number that includes purely i is also imaginary. Complex numbers are a mix of both real and imaginary numbers. for example 3 is real, 5i is imaginary and 3+5i is complex. Hopefully this answers what you meant.
Can a number be imaginary but not pure imaginary?
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
What is 0.2 l?
Not sure what you mean. .2i is an imaginary number, .2l is 1/5 of a liter?
How do you find a negative radical?
Do you mean? - sqrt(4) = - 2 --------or, do you mean, sqrt(- 4) This requires complex (imaginary) numbers sqrt(- 4) = 2i ------
