Chapter 1 - Section 1.6 - Complex Numbers - 1.6 Exercises: 9

Answer

The real part of the complex number ((-2-5i)/3) is -2/3 and the imaginary part is -5/3.

Work Step by Step

Complex numbers are written in the form a+bi, with a being the real number and b being the imaginary number. ((-2-5i)/3) can be rewritten as -(2/3) - (5i/3), making it easier to see that a=-2/3 and b=-5/3, so -2/3 is the real part of the complex number and -5/3 is the imaginary part of the complex number.
