Wykonaj zadania:

a) 3 i 1/4- 5 i 1/6+ 7/12=

=3i3/12-5i2/12+7/12=

3i10/12-5i2/12=

=-1i4/12=

= -1i1/3

 

 

 

b) 1/12 - 1/6- 1/3=

=1/12-2/12-4/12=

= -5/12

 

c)1,5 - 3 i 4/7=

=1i1/2-3i4/7=

=1i7/14-3i8/14=

= -1i5/14

 

d)1 i 3/4+ 5/6=

=1i9/12+10/12=

=1i19/12=

=2i7/12

 

 

Oblicz:

a) 2 i 1/3+3,7=

2i1/3+3i7/10=

=2i10/30+3i21/30=

=5i31/30=

=6i1/30

 

 

b) -2,5-(-1 i 2/9)=

=-2i9/18+1i4/18=

= -1i5/18

 

c) 5,3- 4i 5/6=

5i3/10-4i5/6=

=5i9/30-4i25/30=

=14/30=

=7/15

 

 

d) 4 i 1/3*(-1,5)=

13/3*(-15/10)=

=-195/30=

-6i15/30=

= -6 i 1/2

 

e) -2,5+( -1 i 1/6) =

-2i1/2-1i1/6=

=-2i3/6-1i1/6=

=-3i4/6=

= -3i2/3

 

f) -2,5 : ( - 1 i 1/3) =

-25/10:(-4/3)=

=-25/10*(-3/4)=

=75/40=

=1i35/40=

=1i7/8
