8*4i 1/4 - 11 i1/5 ; 9 i1/3-(-2i 1/3) ;5/3 kr. ułamkowa 14; 2 i2/9+ 8 2/5 * 1 i2/7

Answer 1

 8 * 4 i 1/4  - 11 i 1/5 = 8 * 17/4 - 11 i 1/5 = 34 - 11 i 1/5 = 22 i 4/5

 

9 i 1/3 - ( - 2 i 1/3) = 9 i 1/3 + 2 i 1/3 = 11 i 2/3

 

5/3 : 14= 5/3 * 1/14 = 5/42

 

2 i 2/9 + 8 i 2/5 * 1 i 2/7 = 2 i 2/9 + 42/5 * 9/7 = 2i 2/9 + 54/5 = 2 i 2/9 + 10 i 4/5 = 2 i 10/45 + 10 i 36/45 = 12 i 46/45 = 13 i 1/45
