WebMar 24, 2024 · "The" imaginary number i (also called the imaginary unit) is defined as the square root of -1, i.e., i=sqrt(-1). Although there are two possible square roots of any number, the square roots of a negative number cannot be distinguished until one of the two is defined as the imaginary unit, at which point +i and -i can then be distinguished. Since … WebThus, we can derive a rule for imaginary numbers which is: √(-x) = i √x; These are a part of complex numbers, where a complex number is the sum of a real number and an imaginary number. i.e., a complex number is of the form a + ib, where both 'a' and 'b' are real numbers and here bi is an imaginary number.
