In 3–5 sentences, describe why real numbers and purely imaginary numbers are also complex numbers composed of real and imaginary parts. Also, describe how to identify the real part versus the imaginary part of a complex number.(3 points)
Real numbers and purely imaginary numbers are considered complex numbers because they can both be written in the form a + bi, where a is the real part and bi is the imaginary part. In a real number, the imaginary part is zero, making it a purely real number. In a purely imaginary number, the real part is zero, making it a purely imaginary number. To identify the real part of a complex number, you look at the term without the "i". The imaginary part is the term that includes "i".
