Tôi nhầm rồi

mày tự giải đi

7/1

vì

B.

 \log_a b > \log_a c \Leftrightarrow a>1,\ b<c

• Khi a>1, hàm y=\log_a x đồng biến
  → Phải có:
  \log_a b > \log_a c \Leftrightarrow b > c

❌ Mệnh đề đã ghi ngược chiều (b<c).

B là sai

​​Hi Tom,

I think you should take part in the Ok Om Bok Festival if you have a chance. 🌕 It is a traditional festival of the Khmer people, held to give thanks to the Moon for good harvests. You can enjoy many exciting activities like watching boat races, releasing lanterns, and tasting special foods such as cốm dẹp. The atmosphere is very lively and friendly, so it’s a great way to learn about local culture and meet new people. Don’t forget to take photos and join the celebrations!

Best wishes,

Minh​
