I often call (viết tên trường vào đây mà nhớ là không viết dấu nha, vẫn viết hoa câu đầu) Primary School is my second home. School children, though not very large but very spacious and clean. High school entrance and spacious,the two sides is the flower corridor leads straight to the playground and the classroom. School Grounds are wide, around the yard Poinciana trees and ancient shade cover, with flower beds and lawns green. Listed under the tree row of stone for us to read books and talk after each lesson. The classrooms are full of tables and chairs, cabinets for learning and also exhibited the post office corner, nice arle. In addition, you also have the other classrooms as music room, computer science, library, classrooms English. I even loved the school because here we have good friends and the teachers are always interested to teachand impart knowledge to us. I loved my second home!

I am studying in a gifted school of a big city, so my school is a very interesting place to talk about. We have about 20 classrooms which are divided into three stairs, and they are not including rooms for teachers, canteen, sport and computer rooms. All of our classes are equipped with computers, projectors, microphones, loudspeakers, and some of them even have air conditioners. Next to the classroom block is our library. It is pretty big with a lot of books, and sometimes I think that it contains all of the books that one student may need. Behind it is our mini indoor stadium, where we spend our Physical education classes. Since most of the area is used to build rooms, we have very little place for our school yard. It is only enough for us to sit really close to each other to salute the flag on every Monday. There are just some big trees on the yard, and we have some benches under those trees to rest and enjoy the fresh air. Most of the students stay in their classrooms or go to the canteen during break time since we cannot play anything on the school yard. Fortunately, the canteen is big and comfortable enough for us to spend a good time. There are many different kinds of snacks, drinks as well as chairs there, so we can sit there while eating our favorite food. Because this is a gifted school, studying hours can be very stressful. We need to study for about 8 hours a day, and summer vacation only lasts for a month. Although we have to try really hard to be good enough for the school, I am sure we will miss it very much once we graduate.

Tk mk nha! 

giả sử \(\sqrt{2}\)là số hữu tỉ nên \(\sqrt{2}=\frac{a}{b}\)(với a;b có ước chung lớn nhất là 1)

bình phương 2 vế ta được a² =2b² => a² chia hết cho 2 => a² chia hết cho 4 => a² = 4m (m\(\in N\)*) = 2b² 

=> b² =2m => b² chia hết cho 2 => b chia hết cho  2 => a và b có ước chung lớn nhất khác 1( vô lý)

vậy \(\sqrt{2}\)là số vô tỉ

làm tương tư với các số còn lại

 = 0 nha em

bằng 0
