The square root of a negative value is called an imaginary or complex number.
"A complex number is an element of a number system that contains the real numbers and a specific element denoted by 'i', called the imaginary unit, and satisfying the equation i² = − 1.
Moreover, every complex number can be expressed in the form a + bi, where 'a' and 'b' are real numbers."
Let, a negative number is - 5.
Therefore, the square root of the negative number is:
√(- 5) = 5i
It is an imaginary number. It can be expressed in the form a + bi.
Here, a = 0 and b = 5.
