Step-by-step explanation:
The imaginary part of the number is where i is being multiplied by a constant. The real part is where there is no i present. I'll do a few examples.
26. The real part is 0, since there are no terms that don't have i. The imaginary part is 8i, since i is being multiplied by 8.
27. The real part is 7, since there is no i. The imaginary part is 3i, since i is being multiplied by 3.
31. The real part is 52, since there is no i. The imaginary part is 0i, since i is being multiplied by 0. You don't see the i because zero times i is zero.
