1/5 * (3 i 3/7 - 2/7 * 5 i 1/2) = 1/5 * ( 3 i 6/14 - 4/14 * 11/2) = 1/5 * (3 i 2/14 * 11/2) = 1/2 * (44/14 * 11/2) = 1/2 * 242/14 = 121/14 = 8 i 9/14
3 i 1/5 * 1/2 - 5/7 * 1 i 2/5 = 16/5 * 1/2 - 5/7 * 7/5 = 8/5 - 1 = 1 i 3/5 - 1 = 3/5
(1 i 2/3)² * (3 i 1/6 - 2 2/3) = (5/3)² * (3 i 1/6 - 2 i 4/6) = 25/9 * ( 2 i 7/6 - 2 i 4/6) = 25/9 * 3/6 = 25/18 = 1 i 7/18
