Accepted Solution

A:

Answer: Last option.Step-by-step explanation: Real numbers are defined as those numbers that can be found on the number line. By definition Pure imaginary numbers have no real part. When the real part is zero we often will call the complex number a purely imaginary number By definition, Complex numbers have the following form: [tex]a + bi[/tex] Where "a" and "b" are real numbers and "i" is the the imaginary unit (Remember that [tex]i=\sqrt{-1}[/tex]) Based on the explained before, and given the following number: [tex]3-719i[/tex] You can conclude that it is Complex number, because it has the form [tex]a + bi[/tex]
