Complex Number Definition

A number that is written in the form of a+ib where i is an imaginary term and a and b are real numbers is called a Complex Number. The value of i is √-1. A complex number has two parts, Real Part and Imaginary Part. The real part consists of the real number ‘a’ while ‘ib’ is the imaginary part.

Complex Number Power Formula

Complex Numbers are numbers that can be written as a + ib, where a and b are real numbers and i (iota) is the imaginary component and its value is √(-1), and are often represented in rectangle or standard form. 10 + 5i, for example, is a complex number in which 10 represents the real component and 5i represents the imaginary part. Depending on the values of a and b, they might be wholly real or purely fictitious. When a = 0 in a + ib, ib is a totally imaginary number, and when b = 0, we get a, which is a strictly real number.

In this article, we will learn about, complex number power formulas, their examples, and others in detail.
