Just take the square root, and put a minus sign in front of it.
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.
x = (-b plus_minus root(b2 - 4ac)) / 2aWhere plus_minus is the "plus or minus" sign, and "root" stands for the square root.
The square root of negative one is an imaginary number, signified by the italic lower-case i.
Negative square root is -√Square root of negative one is i.
There is no real answer. The square root of negative one is denoted i for imaginary.
Just take the square root, and put a minus sign in front of it.
It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.
I, the square root of -1
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
The square root of -6400 is not a real number because the square root of a negative number is not defined in the real number system.
A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.
x = (-b plus_minus root(b2 - 4ac)) / 2aWhere plus_minus is the "plus or minus" sign, and "root" stands for the square root.
square roots of a negative number are imaginary, where i = square root (-1) sqrt (-2500) = sqrt (2500) i = 50 i
The square root of negative one is an imaginary number, signified by the italic lower-case i.
