Question

THE SQUARE ROOT OF A NEGATIVE NUMBER IS NOT REAL. ITS IMAGINARY ANDI IT IS DENOTED BY?

Answer 1

According to the definition if the complex number (a, b) be denoted by z then z = (a, b) = a + ib (a, b ϵ R) where a is called the real part, denoted by Re(z) and b is called imaginary part, denoted by Im (z).

Answer 2

The term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero, which has one double square root.
