Đầu kiện: \(a>0;a\ne1\)

\(P=\left(\dfrac{4a}{\sqrt{a}-1}-\dfrac{\sqrt{a}}{\sqrt{a}\left(\sqrt{a}-1\right)}\right).\dfrac{\sqrt{a}-1}{a^2}\\ =\dfrac{4a-1}{\sqrt{a}-1}.\dfrac{\sqrt{a}-1}{a^2}\\ =\dfrac{4a-1}{a^2}\)

b.

\(P=3\Leftrightarrow\dfrac{4a-1}{a^2}=3\\ \Leftrightarrow3a^2-4a+1=0\)

\(\Rightarrow\left[{}\begin{matrix}a=1\\a=\dfrac{1}{3}\end{matrix}\right.\)

So với đầu kiện bài toán ta có a = 1/3 thõa mãn bài toán.

Minh chú ý là Điều kiện, ko phải Đầu kiện nhé

Good morning teacher and everyone!

Today, on behalf of my group, I am very glad to present to you about our plan for one-day trip to a place of interest. First of all, after discussing, we came up with the decision to go to Thong Nhat Park for a picnic in Sunday. The reasons for this choice are that Thong Nhat park is located right in Ha Noi so it does not take much time to get there and we can have more time to enjoy the trip; this park is really large so there is plenty of space for picnic and other outdoors activities. Secondly, we made a detailed plan for this trip. To specify, we will gather at school and set off at 9 a.m on Sunday by bicycle altogether. On arrival, An, Binh and Chien will be responsible for pitching a tent while Hoa and I prepare the lunch for us. After that, we will have lunch together and chat with each other. Binh will bring his guitar so we will sing together our favorite songs. In the afternoon, we will wander around to park and enjoy the fresh air there. We will go home at 5 p.m. I am really looking forward to carrying this plan out with my friends in this weekend.

Thank you for listening to my presentation and if you like our plan, please vote for our group
