Odpowiedź:

2/3 * 1 i 4/5 + 2 i 1/2 = 2/3 * 9/5 + 2 i 1/2 = 6/5 + 2 i 1/2 = 12/10 + 2 i 5/10 = 2 i 17/10 = 3 i 5/10 = 3 i 1/2

((1 i 1/2)² + 1 i 1/6)) * 3 = ((3/2)² + 1 i 1/6)) * 3 = (9/4 + 1 i 1/6) * 3 = (27/12 + 1 i 2/12) * 3 = 1 i 29/12 * 3 = 41/12 * 3 = 123/12 = 10 i 3/12 = 10 i 1/4

4 i 7/8 - 1 i 1/3 * 1 i 1/8 = 4 i 7/8 - 4/3 * 9/8 = 4 i 7/8 - 3/2 = 4 i 7/8 - 1 i 1/2 =

4 i 7/8- 12/8 = 3 i 15/8 - 12/8 = 3 i 3/8
