Explicație pas cu pas:
2/33 - 3/22 = 4/66 - 9/66 = -5/66
a = 2/33 + I-5/66I = 2/33 + 5/66 = 4/66 + 5/66 = 9/66 = 3/22
_______
3/12 - 4/10 = 1/4 - 2/5 = 5/20 - 8/20 = -3/20
b = 2/20 - I-3/20I = 2/20 - 3/20 = -1/20
________
a > 0
b < 0
a > b
Răspuns:
a=2/33+|2/33-3/22|=
=4/66+|4/66-9/66|=
=4/66+|-5/66|=
=4/66+5/66=
=9/66=
=3/22
b=2/20-|3/12-4/10|=
=6/60-|15/60-24/60|=
=6/60-|-9/60|=
=6/60-9/60=
=-3/60=
=-1/20
a>b
