Olm chào em. Đây là toán nâng cao chuyên đề so sánh phân số có chứa lũy thừa, cấu trúc thi chuyên, thi học sinh giỏi các cấp. Hôm nay, Olm sẽ hướng dẫn các em giải chi tiết dạng này như sau:

Giải:

B = \(\frac{10^{20}+1}{10^{21}+1}\)

Vì 10\(^{20}\) + 1 < 10\(^{21}\) + 1

Áp dụng ct:

\(\frac{a}{b}\) < \(\frac{a+n}{b+n}\) (a; b; n ∈ N*; a < b)

Ta có:

B = \(\frac{10^{20}+1}{10^{21}+1}\) < \(\frac{10^{20}+1+9}{10^{21}+1+9}\) = \(\frac{10^{20}+\left(1+9\right)}{10^{21}+\left(1+9\right)}=\frac{10^{20}+10}{10^{21}+10}\)

B = \(\frac{10^{20}+1}{10^{21}+1}\) < \(\frac{10^{}.\left(10^{19}+1\right)}{10.\left(10^{20}+1\right)}\) = A

Vậy A > B

Dear Anna,

Last month, my school organized a one-day trip to Bat Trang pottery village. We left school at 7 a.m. and arrived there about one hour later. Although the weather was quite hot, everyone was excited about the trip.

First, we visited a small museum where we learned about the history of pottery making in Vietnam. Then, a local artist showed us how to make bowls, cups and animal toys from clay. After that, we tried making our own products. Mine was not very beautiful, but I still felt happy because it was my first time doing this activity.

At noon, we had lunch in a small restaurant near the Red River. The food was delicious, especially the fried spring rolls. In the afternoon, we walked around the village and bought some souvenirs for our families and friends. I bought a small blue vase for my mother.

We returned to school at 5 p.m. Everyone was tired but very happy. The trip helped us learn more about traditional Vietnamese culture and gave us many wonderful memories.

Best wishes,
Phong
