Computer currently helps me much in my study.

First of all, it helps me format my lessons effectively. I often type my lessons on the computer and format them to make them attractive to eyes so that I may learn them by heart quickly and review them conveniently.

Next, computer helps me keep my materials safely for future use. Today, beside the hard drive, I often bring my USB’s with me and use them to save all what I want at any time and place.

Moreover, I often updatemy materials on the screen. This enables me to create clear and tidy versions of materials and save up much time for other activities. On the other hand, computer is the most helpful friend helping me learn information and knowledge on the internet.

Thanks to computer, I often access the internet and learn many things. Computer has made my understanding better day by day and become indispensable for my study.

When they first came to Australia, because they wanted to get acquainted with their new friends, Trang blurted them to the party house. At the head of crazy guests to the house, she opened the door to invite them, do not forget to sit in courtesy. So when they say 'Have a seat', both of them turned to look at the page was surprised. Not knowing what happened, she stabbed in confusion.
It turned out that the wrong pronunciation of the word "seat" to "shit" has created such an irony. May Trang live with a Vietnamese sister, she understood the idea should explain to everyone. After listening, the whole group was laughing and Trang was very embarrassed.


Mình dịch có vài chỗ chưa chuẩn lắm. Bạn thông cảm nha!!

S = 2¹ + 2² + 2³ + ... + 2¹⁰²

  2S = 2² + 2³ + 2⁴ + ... + 2¹⁰³

2S - S =  ( 2² + 2³  + 2⁴ + ... + 2¹⁰³) - (2 + 2² + 2³ + ... + 2¹⁰²)

             =  2¹⁰³ - 2 

Thay vào ta được:

     2¹⁰³ - 2 + 2 = 2ⁿ

2¹⁰³ = 2ⁿ

=>  n = 103

I’m having an apartment at 9.30.
