Question

Compara numerele a=2/33 +| 2/33-3/22 |. Și B=2/20 - |3/12 - 4/10 |

Answer 1

Răspuns:

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

Answer 2

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
