Consider the complex numbers t = -6 + 41, u = -51, w= 4, and z = 3 - 81. On the complex plane shown, t has been plotted. Question: A. What are the real and imaginary parts of t? Are the real part and the imaginary part real numbers or imaginary numbers? What does i represent? B. What are the real and imaginary parts of u and w? Are u and w real numbers or imaginary numbers? What does this tell you about the relationship between real numbers, imaginary numbers, and complex numbers? C. Plot z on a complex plane.​
