Answers and Explanations -- Do "Imaginary Numbers" Really Exist?

WebA complex number is a number of the form a + b i where. a. a is the real part of the complex number. b. b is the imaginary part of the complex number. If b = 0, then a + b i is a real number. If a = 0 and b is not equal to 0, the complex number is called a pure imaginary number. An imaginary number is an even root of a negative number. WebThe real number a is written as a+0i a + 0 i in complex form. Similarly, any imaginary number can be expressed as a complex number.
