Answer 1

a)
1 i 4/9 * 12 + 13/9 * 12 = 52/3 = 17 i 1/3

6 * 2 i 1/2 = 6 * 5/2 = 15

2 i 3/8 * 12 = 19/8 * 12 = 57/2 = 28 i 1/2

(1 i 1/4)^2 = (5/4)^2 = 25/16 = 1 i 9/16

(1 i 1/4)^3 = (5/4)^3 = 125/64 = 1 i 61/64

b)
4 i 2/7 * 3 i 1/2 = 30/7 * 7/2 = 15

8 i 1/3 * 2 i 2/5 = 25/3 * 12/5 = 20

4 i 1/5 * 2 i 1/7 = 21/5 * 15/7 = 9

(1 i 2/3)^3 = (5/3)^3 = 125/7 = 4 i 17/27

(2 i 1/2)^2 = (5/2)^2 = 25/4 = 6 i 1/4

Answer 2

1 4/9*12=13/9*12=52/3=17 1/3
6*2 1/2=6*5/2=8
2 3/8*12=19/8*12=57/2=28 1/2
