Calculati |x•y| si |x|•|y| pentru:
a)x=4,y=6
b)x=5,y=6
c)x=2,x=9
d)x=10,y=18
e)x=-5,y=7
f)x=-4,y=8
g)x=-3,y=9
h)x=-1,y=12
i)x=7,y-3
j)x=8,y=-12
k)x=3,y=-2
l)x=10,y=-13

URGENTTTTTT!!!!!!!!!!
DAU COROANA!!!!!!!!!!

Răspuns :

a)|x×y|=24
|4|×|6|=24
b)|5×6|=30
|5|×|6|=30
c)|2×9|=18
|2|×|9|=18
d)|10×18|=180
|10|×|18|=180
e)|(-5)×7|=|-35|=35
|-5|×|7|=5×7=35
f)|(-4)×8|=|-32|=32
|-4|×|8|=32
g)|(-3)×9|=|-27|=27
|-3|×|9|=3×9=27
h)|(-1)×12|=|-12|=12
|-1|×|12|=12
i)|7×(-3)|=|-21|=21
|7|×|-3|=7×3=21
j)|8×(-12)|=|-96|=96
|8|×|-12|=8×12=96
k)|3×(-2)|=|-6|=6
|3|×|-2|=3×2=6
l)|10×(-13)|=|-130|=130
|10|×|-13|=10×13=130
de fapt aceasta este o proprietate a modulului
|xy|=|x|•|y|
