WebTo divide complex numbers. First, find the complex conjugate of the denominator, multiply the numerator and denominator by that conjugate and simplify. Example 1. Let's divide … WebDividing Complex Numbers. Division of two complex numbers is more complicated than addition, subtraction, and multiplication because we cannot divide by an imaginary number, meaning that any fraction must have a real-number denominator. This idea is similar to rationalizing the denominator of a fraction that contains a radical.

Webi 2 = ( − 1) 2 = − 1. We can write the square root of any negative number as a multiple of i. Consider the square root of –25. − 25 = 25 ⋅ ( − 1) = 25 − 1 = 5 i. We use 5 i and not − 5 i because the principal root of 25 is the positive root. A complex number is the sum of a real number and an imaginary number. WebTo divide complex numbers.
