Answer:

z = 3 + i is complex as a,b\in \mathbb{R}, b \neq 0.

Step-by-step explanation:

A complex number comprehends all numbers of the form:

z = a+i\cdot b, \forall \,a,b\in \mathbb{R}

Where i = \sqrt{-1}.

In other words, complex numbers are an extension of real numbers.

There is the following classification depending on what values of a and b exist:

Real - a \in \mathbb{R}, b = 0

Complex - a,b\in \mathbb{R}, b \neq 0  

Pure imaginary - a = 0, b \neq 0 (The term "nonreal complex" is a synonym for pure imaginary complex)

Let be z = 3 + i, which is complex as a,b\in \mathbb{R}, b \neq 0.
