Topic 1:

During an earthquake, we should stay calm and quickly find a safe place to hide, such as under a strong table or next to a wall. We must protect our head and avoid running outside because falling objects can be dangerous. We shouldn’t use elevators or stand near windows. After the shaking stops, we should move to an open area and wait for help.

Trong cuộc sống xưa và nay con người tồn tại song hành cùng với môi trường xung quanh họ. Bất cứ thứ gì bên ngoài cơ thể xung quanh ta đều có mối liên hệ với cuộc sống. Mà trong đó đồ vật gắn bó và gần gũi, cần thiết, không thể thiếu với mỗi người chính là quần áo. Đó là thứ giữ ấm cho cơ thể khi trời lạnh, che cho ta khỏi sự gắt gay của nắng hè, thậm chí là âm thầm giúp ta giấu đi những khuyết điểm của cơ thể, nhẹ nhàng tôn lên những nét duyên dáng, từ đó khiến hình ảnh của bạn trong mắt người khác được đẹp đẽ, đáng yêu, thân thiện và hấp dẫn.

A = 3.3.3.3...3 + 7.7.7.7...7 (2025 thừa số 3; 2025 thừa số 7)

Đặt B = 3.3.3....3 (2025 thừa số 3)

C = 7.7.7...7(2025 thừa số 7)

Vì 2025 : 4 = 506 dư 1 nên ta nhóm 4 thừa số liên tiếp của B vào nhau, khi đó:

B = (3.3.3.3).(3.3.3.3)...(3.3.3.3).3

B = \(\overline{..1}\).\(\overline{..1}\)....\(\overline{..1}\) . 3

B = \(\overline{..1}\). 3

B = \(\overline{..3}\)

C = (7.7.7.7).(7.7.7.7)...(7.7.7.7).7

C = \(\overline{..1}\).\(\overline{..1}\)...\(\overline{..1}\) .7

C = \(\overline{..7}\)

A = B + C = \(\overline{..3}+\overline{..7}\) = \(\overline{..0}\)

Vậy chữ số tận cùng của A là 0
