Answer 1

Răspuns:

4 567 = 4000 + 500 +60 +7

4 567 = 4 × 1000 + 5 × 100 + 6 ×10 +7

8 642 = 8000 + 600 + 40 + 2

8 642 = 8×1000+6×100+4×10+2

9 135 = 9000+100+30+5

9 135= 9×1000+1×100+3×10+5

21 648 = 20 000 +1000 + 600 + 40 + 8

21 648 =2×10 000+1×1000+6×100+4×10+8

53 849= 50 000 +3000+800+40+9

53 849 = 5×10 000+3×1000+8×100+4×10+9

75 028 = 70 000+ 5000+20 +8

75 028 = 7×10 000+5×1000+2×10+8

841 649 = 800 000 + 40 000 +1000+600+40+9

841 649=8×100 000+4×10 000+1×1000+6×100+

4×10 +9

950 354 = 900 000+50 000+300+50+4

950 354= 9 ×100 000+5×10 000+3×100+5×10+4

634 258=600 000+30 000+4000+200+50+8

634 258=6×100 000+3×10 000+4×1000+2×100+

5×10+8
