What Is Dividing Complex Numbers

Dividing complex is mathematically similar to the division of two real numbers.

Dividing complex numbers is a little more complicated than addition, subtraction, and multiplication of complex numbers because it is difficult to divide a number by an imaginary number.

Dividing Complex Numbers Formula:

A+Bi\C+Di

(A+bi)(c-di)/(c+di)(c-di)

• $$\frac{7}{17}+\frac{8i}{22}$$

• $$\frac{5}{18}+\frac{9i}{33}$$
