Question

1 2/3 : 2 1/2 + 9 x 1 1/6=
(1 1/2) do potęgi 2 - 1 3/5: 2 2/3=
3 1/4 : (2 5/8 - 1 1/6) : 2 1/2)=

Answer 1

1 i 2/3 : 2 i 1/2 + 9 * 1 i 1/6 =

= 5/3 : 5/2 +9 * 7/6=

= 5/3 * 2/5 + 3 * 7/2=

= 1/3 * 2/1 + 21/2=

= 2/3 + 10 i 1/2=

= 4/6 + 10 i 3/6=

= 10 i 7/6=

= 11 i 1/6




(1 i 1/2)^2 - 1 i 3/5 : 2 i 2/3=

= (3/2)^2 - 8/5 : 8/3=

= 9/4 - 8/5 * 3/8 =

= 2 i 1/4 - 1/5 * 3/1 =

= 2 i 1/4 - 3/5=

= 2 i 5/20 - 12/20=

= 1 i 25/20 - 12/20=

= 1 i 13/20





3 i 1/4 : ( (2 i 5/8 - 1 i 1/6) : 2 i 1/2)=

= 13/4 : ( (2 i 15/24 - 1 i 4/24) : 5/2)=

= 13/4 :(1 i 11/24 : 5/2)=

= 13/4 : (35/24 * 2/5)=

= 13/4 :(7/12 * 1/1)=

= 13/4 : 7/12=

= 13/4 * 12/7=

= 13/1 * 3/7=

= 39/7=

= 5 i 4/7
