The best measure of the center for second period is Mean, because there are no outliers that affect the center.
(5+3i)(8-2i). We will FOIL this out like anything else. 5*8 = 40; 5*2i = 10i; 3i*8 = 24i; 3i*-2i = -6i^2. Putting that all together we have 40+10i+24i-6i^2. Simplifying we have 40+34i-6i^2. i^2 = -1, s0 -6*-1=6. Now let's rewrite. 40+34i+6 = 46 + 34i. That's the product.
