Question

7) Calculează, asociind convenabil factorii:
2 x 46 x 50 =
14 x 5 x 5 x 2 =
25 x 23 x 4 =
2 x 25 x 17 x 2 =​

Answer 1

2×46×50 = (2×50)×46  

= 100×46  

= 4600

25×23×4 = (25×4)×23  

= 100×23  

= 2300

14×5×5×2 = (5×2)×(5×14)  

=10×(5×14)  

=10×70  

= 700

2×25×17×2 = (2×25)×(17×2)  

=50×34  

=1700
