Online learning has emerged as a convenient and effective alternative to traditional classroom instruction. In this essay, I firmly agree with the statement that online learning not only offers convenience but also proves to be more effective than traditional classroom teaching. Firstly, online learning provides unmatched convenience for both students and teachers. With the click of a button, students can access course materials, lectures, and assignments at any time and from any location. This flexibility allows individuals to tailor their learning experience around their personal schedules, enabling them to balance work, family commitments, and education effectively. Moreover, online platforms eliminate the need for lengthy commutes and provide an inclusive learning environment, as students from various geographic locations can access the same resources and expertise. Secondly, online learning has demonstrated its effectiveness through improved outcomes and engagement. The personalized nature of online courses allows students to progress at their own pace, ensuring a thorough understanding of the subject matter. Adaptive learning tools and assessments help identify areas of weakness and provide targeted interventions, enabling students to strengthen their knowledge gaps. Additionally, online platforms often incorporate interactive multimedia, simulations, and gamification techniques, which enhance student engagement and promote active learning. Furthermore, online learning encourages the development of valuable digital skills that are increasingly vital in today's technology-driven world. Students become proficient in navigating online platforms, utilizing digital resources, and collaborating in virtual environments. These skills are transferable to various professional settings and enhance students' employability prospects. While face-to-face interactions are seen as a strength of traditional classrooms, online learning has adapted by incorporating discussion forums, video conferencing, and group projects. These tools foster meaningful interactions, promote peer learning, and create a sense of community among students. In conclusion, online learning offers unparalleled convenience, personalized learning experiences, and the development of digital skills. Its flexibility and effectiveness make it a superior alternative to traditional classroom instruction. By embracing online learning, we can create a more accessible and efficient education system that meets the diverse needs of students and teachers in the modern world.

giải thích bằng tiếng anh đó, có gì bạn tra gg dịch hoặc trang dịch nhé

1. A

The sentence "What a pity my wife can't speak English" expresses regret that the wife does not speak English. The rewritten sentence "I wish my wife could speak English" also expresses regret, but it does so in a more indirect way. The word "wish" indicates that the speaker would like the wife to speak English, and the modal verb "could" indicates that the speaker believes it is possible for the wife to learn English.

2. C

The original sentence tells us that the man called the police and that his wallet had been stolen. The rewritten sentence tells us the same thing, but it uses the relative pronoun "whose" to clarify that the wallet belonged to the man. The use of the past perfect tense "had been stolen" indicates that the wallet was stolen before the man called the police.

3. C

The original sentence tells us that English people speak quickly and that this is why the speaker cannot understand them. The rewritten sentence expresses the same idea, but it uses the conditional "if" to show that the speaker is imagining a different situation. In this imagined situation, English people do not speak quickly, and the speaker is therefore able to understand them.

4. D

The original sentence tells us that the last time the speaker saw Peter was on Sunday. The rewritten sentence expresses the same idea, but it uses the phrase "since Sunday" to show that the speaker has not seen Peter since that day.

5. A

The original sentence tells us that the city used to have old buildings, but that none of these buildings can be found nowadays. The rewritten sentence expresses the same idea, but it uses the phrase "there used to be" to show that the old buildings no longer exist.

6. C

The original sentence tells us that we should turn off all the lights before going out. The rewritten sentence expresses the same idea, but it uses the modal verb "must" to show that it is obligatory to turn off the lights before going out.

7. D

The original sentence tells us that the speaker would prefer if the sofa were delivered on Saturday. The rewritten sentence expresses the same idea, but it uses the phrase "I would rather" to show that the speaker has a strong preference for the sofa being delivered on Saturday.

8. D

The original sentence tells us that the speaker's father told him never to borrow money from friends. The rewritten sentence expresses the same idea, but it uses the modal verb "to" to show that the speaker's father was giving him a direct instruction.

9. A

The original sentence tells us that somebody repaired the speaker's refrigerator last month. The rewritten sentence expresses the same idea, but it uses the phrase "had somebody repair" to show that the speaker arranged for somebody to repair the refrigerator.

10. B

The original sentence tells us that the novel was so interesting that the speaker read it many times. The rewritten sentence expresses the same idea, but it uses the phrase "such an interesting novel" to emphasize how interesting the novel was.

tớ cg đúng mà

Bài toán không rõ ràng nên mình chia ra làm hai cái nhé.

----

ĐỀ 1: Chứng minh rằng `i+u+v+uv=(i+u)(i+v)` với mọi `u,i,v`

Ta có: `(i+u)(i+v)=i(i+v)+u(i+v)=i^2+iv+ui+uv\ne i+u+v+uv`

Vậy đề sai

-----

ĐỀ 2: Tìm điều kiện `u,i,v` để `i+u+v+uv=(i+u)(i+v)` đúng

`(i+u)(i+v)= i+u+v+uv`

`<=>i^2+iv+ui+uv= i+u+v+uv`

`<=>i^2-i+iv-v+ui-u=0`

`<=>i(i-1)+v(i-1)+u(i-1)=0`

`<=>(i-1)(i+v+u)=0`

`=>i=1` hoặc `i+u+v=0`

Đặt `t=x-\sqrt3=>x=t+sqrt3( t\inZZ)`

Khi đó: `x^2+2sqrt3=(t+sqrt3)^2+2sqrt3=t^2+3+2sqrt3(t+1)\inZZ`

`=>t+1=0<=>t=-1`

`=>x=-1+sqrt3,` thử lại ta đều thấy `(sqrtx-3;x^2+2\sqrt3;x-2/x)\inZZ`

Vậy `x=-1+sqrt3`
