You're on a roll — To find the real and imaginary parts of a complex number z = a+bi, the real part is a and the imaginary part is b. i) -3 - 4i Step 1: Identify the real and imaginary components. The real part is the term without i. The imaginary part is the coefficient of i. Real part: -3 Imaginary part: -4 ii) 20 + 4i Step 1: Identify the real and imaginary components. Real part: 20 Imaginary part: 4 iii) -1 - 2i Step 1: Identify the real and imaginary components. Real part: -1 Imaginary part: -2 iv) 4 - i Step 1: Identify the real and imaginary components. Note that -i is equivalent to -1i. Real part: 4 Imaginary part: -1 Drop the next question.
