DAU COROANA! ​

Answer 1

Răspuns:

Explicație pas cu pas:

2 x 25 x 5 x 4 = (2x5)x(25x4) = 10x100 = 1000

8 x 25 x 5 x 2 = (8x5)x(25x2) = 40x50 = 2000

sau

8 x 25 x 5 x 2 = (8x25)x(5x2) = 200x10 = 2000

50x3x2 = (50x2)x3 = 100x3 = 300

8x500x4 = 8x(500x4) = 8x2000 = 16000

sau

8x500x4 = (8x500)x4 = 4000x4 = 16000

Answer 2

1)(2*5)*(25*4)=10*100=1000

2)(8*25)*(5*2)=200*10=2000

3)(50*2)*3=100*3=300

4)(500*4)*8=2000*8=16000
