X + 197 = 298

X           = 298 - 197

X            = 101

C. 101

= 4590

điểm âm của mik chỉ còn 158 nữa thôi, các bn giúp mik nha

Khi nào hết âm mik sẽ ra câu hỏi và giúp lại các bn

Cảm ơn trc~ 

459 + 459 × 8 +459

=4590

nha bn!mk nhanh nhất.(mk đang bị âm)k mk nha

số đó là

459x3x8

=11016

ai  k mình thì mình

k lại cho

= 459 +459 ×8 +459 

= 4590 !

a) 13 876 = 10 000 + 3 000 + 800 + 70 + 6

b) 204 038 = 200 000 + 4 000 + 30 + 8

c) 50 877 = 50 000 + 800 + 70 + 7

d) 8 672 980 = 8 000 000 + 600 000 + 70 000 + 2 000 + 900 + 80

Phương pháp giải:

- Xác định khoảng cách giữa hai số liên tiếp.

- Đếm cách rồi điền số còn thiếu vào chỗ trống. 

Lời giải chi tiết:

a) 100; 200; 300; 400; 500; 600; 700; 800; 900; 1000.

b) 910; 920; 930; 940; 950; 960; 970; 980; 990; 1000.

c) 514; 515; 516; 517; 518; 519; 520; 521; 522; 523.
