Nhớ tích nhé!

Có một câu chuyện cổ tích mà em có thể thích. Đó là câu chuyện về "Ông Ba Mươi". Một lần kia, có một người đàn ông tên là Ông Ba Mươi. Ông Ba Mươi là một người rất tốt bụng và luôn sẵn lòng giúp đỡ mọi người xung quanh. Một ngày nọ, Ông Ba Mươi gặp một cậu bé đang khóc. Cậu bé nói rằng mình đã bị mất một số tiền quan trọng. Ông Ba Mươi không ngần ngại, ông đã giúp cậu bé tìm lại số tiền đó. Sau đó, Ông Ba Mươi còn giúp đỡ nhiều người khác trong làng. Mọi người đều biết đến Ông Ba Mươi là một người tốt và rất biết giúp đỡ người khác. Câu chuyện về Ông Ba Mươi nhắc nhở chúng ta về tình yêu thương và lòng nhân ái.

I have been studying English since I was in secondary, and I realized that I had gain a lot of benefits from learning that language. First, English makes me become much more confident in communicating and expressing my opinion. Through practicing in speaking class, I can develop both my communicating and pronouncing skills. Second, English is a good supporting subject for my writing skill. By following the available grammars, I can gradually know how to make more convincing arguments as well as give demonstrating examples. Third, listening skill helps me to have more focus to the details in every conversation. In that way I can collect more valuable information in just a short time. Besides, I can also develop me note-taking skills since it is necessary to have a good note while I am listening to lectures. Last, what I had learnt in reading skill can be applied perfectly in reading any kind of material. By scanning and skimming, I can understand thoroughly the main ideas of each page. In sum up, all of the four skills of English can particularly help me in a lot of aspects. I am happy that I started learning English at a very young age, and I will continue to practice it

Đề 1:

Bài 1:

\(a,=\sqrt{\left(\sqrt{7}+1\right)^2}-\left|-1+\sqrt{7}\right|=\sqrt{7}+1-\sqrt{7}+1=2\\ b,=2\sqrt{2}-4\sqrt{2}-5\sqrt{2}+\dfrac{\sqrt{2}}{2}=\dfrac{\sqrt{2}}{2}-7\sqrt{2}=\dfrac{-13\sqrt{2}}{\sqrt{2}}\)

Bài 2:

\(PT\Leftrightarrow\sqrt{\left(x-\dfrac{1}{2}\right)^2}=\dfrac{1}{2}\Leftrightarrow\left|x-\dfrac{1}{2}\right|=\dfrac{1}{2}\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{1}{2}+\dfrac{1}{2}=1\\x=-\dfrac{1}{2}+\dfrac{1}{2}=0\end{matrix}\right.\)

Bài 3:

\(a,M=\dfrac{a-2\sqrt{a}+1}{\sqrt{a}\left(\sqrt{a}-1\right)}\cdot\dfrac{2\sqrt{a}}{\left(\sqrt{a}-1\right)\left(\sqrt{a}+1\right)}=\dfrac{2\left(\sqrt{a}-1\right)^2}{\left(\sqrt{a}-1\right)^2\left(\sqrt{a}+1\right)}=\dfrac{2}{\sqrt{a}+1}\\ b,M< 1\Leftrightarrow\dfrac{2}{\sqrt{a}+1}-1< 0\Leftrightarrow\dfrac{1-\sqrt{a}}{\sqrt{a}+1}< 0\\ \Leftrightarrow1-\sqrt{a}< 0\left(\sqrt{a}+1>0\right)\\ \Leftrightarrow a>1\)

`30 000-15 273-4727`

`= 30 000-(15 273+4727)`

`=30 000-20000`

`=10 000`

`49 573-(25 000+9573)`

`=49 573-25 000-9573`

`=(49 573-9573)-25 000`

`=40000-25000`

`=15000`

giúp em đi ạ em cần gấp lắm rồi

a: =30000-20000=10000

b: =40000-25000=15000
