What is the complex conjugate of a real number? For a real number, we can write z = a+0i = a for some real number a. So the complex conjugate z∗ = a − 0i = a, which is also equal to z. So a real number is its own complex conjugate. [Suggestion : show this using Euler’s z = r eiθ representation of complex numbers.] Exercise 8.
