Bài 1:1) \(10+2\sqrt{10}=\sqrt{10}\left(2+\sqrt{10}\right)\)

2) \(7+3\sqrt{7}=\sqrt{7}\left(3+\sqrt{7}\right)\)

các câu 3,4,5 bạn làm tương tự như 2 câu trên

6) \(3a\sqrt{b}+3b\sqrt{a}=3\sqrt{ab}\left(\sqrt{a}+\sqrt{b}\right)\)

7) \(a^2-2a\sqrt{2}+2=a^2-2a\sqrt{2}+\left(\sqrt{2}\right)^2=\left(a-\sqrt{2}\right)^2\)

8) \(b-4=\left(\sqrt{b}\right)^2-2^2=\left(\sqrt{b}-2\right)\left(\sqrt{b}+2\right)\)

Bài 2: 1) \(\dfrac{\left(2-\sqrt{a}\right)^2-\left(\sqrt{a}+3\right)^2}{2a+\sqrt{a}}\left(a>0\right)\)

\(=\dfrac{\left(2-\sqrt{a}-\sqrt{a}-3\right)\left(2-\sqrt{a}+\sqrt{a}+3\right)}{\sqrt{a}\left(2\sqrt{a}+1\right)}\)

\(=\dfrac{\left(-2\sqrt{a}-1\right).5}{\sqrt{a}\left(2\sqrt{a}+1\right)}=-\dfrac{5}{\sqrt{a}}\)

3) \(\dfrac{a+4\sqrt{a}+4}{\sqrt{a}+2}+\dfrac{4-a}{\sqrt{a}-2}\left(a\ge0,a\ne4\right)\)

\(=\dfrac{\left(\sqrt{a}+2\right)^2}{\sqrt{a}+2}+\dfrac{\left(2-\sqrt{a}\right)\left(2+\sqrt{a}\right)}{\sqrt{a}-2}=\sqrt{a}+2-\left(2+\sqrt{a}\right)=0\)

4) \(\left(1-\dfrac{a-\sqrt{a}}{\sqrt{a}-1}\right)\left(1-\dfrac{a+\sqrt{a}}{1+\sqrt{a}}\right)\left(a\ge0,a\ne1\right)\)

\(=\left(1-\sqrt{a}\right)\left(1-\sqrt{a}\right)=\left(1-\sqrt{a}\right)^2=a-2\sqrt{a}+1\)

mấy câu còn lại bạn làm tương tự

Bài 1: 

1) \(10+2\sqrt{10}=2\sqrt{5}\left(\sqrt{5}+\sqrt{2}\right)\)

2) \(7+3\sqrt{7}=\sqrt{7}\left(\sqrt{7}+3\right)\)

3) \(5\sqrt{7}-7\sqrt{5}=\sqrt{35}\left(\sqrt{5}-\sqrt{7}\right)\)

4) \(4\sqrt{3}-2\sqrt{6}=2\sqrt{6}\left(\sqrt{2}-\sqrt{1}\right)\)

5) \(6\sqrt{6}-2\sqrt{12}+3\sqrt{2}\)

\(=\sqrt{216}-\sqrt{48}+\sqrt{18}\)

\(=\sqrt{6}\left(6-2\sqrt{2}+\sqrt{3}\right)\)

6) \(3a\sqrt{6}+36\sqrt{a}\)

\(=3\sqrt{a}\left(\sqrt{6a}+12\right)\)

\(=3\sqrt{6a}\left(\sqrt{a}+2\sqrt{6}\right)\)

7) \(a^2-2a\sqrt{2}+2=\left(a-\sqrt{2}\right)^2\)

8) \(b-4=\left(\sqrt{b}-2\right)\left(\sqrt{b}+2\right)\)

Bài 2: 

a) Ta có: \(\dfrac{\left(2-\sqrt{a}\right)^2-\left(\sqrt{a}+3\right)^2}{2a+\sqrt{a}}\)

\(=\dfrac{a-4\sqrt{a}+4-a-6\sqrt{a}-9}{2a+\sqrt{a}}\)

\(=\dfrac{-10\sqrt{a}-5}{\sqrt{a}\left(2\sqrt{a}+1\right)}\)

\(=\dfrac{-5\left(2\sqrt{a}+1\right)}{\sqrt{a}\left(2\sqrt{a}+1\right)}\)

\(=-\dfrac{5}{\sqrt{a}}\)

4) Ta có: \(\left(1-\dfrac{a-\sqrt{a}}{\sqrt{a}-1}\right)\left(1-\dfrac{a+\sqrt{a}}{1+\sqrt{a}}\right)\)

\(=\left(1-\sqrt{a}\right)\left(1-\sqrt{a}\right)\)

\(=a-2\sqrt{a}+1\)

Nhận xét về nhân vật Hồ Quý Ly:

trong tình trạng đất nước khủng hoảng, ông đã mạnh dạn khởi xướng và tiến hành thực hiện cuộc cải cách trên nhiều mặt nhằm đưa đất nước thoát khỏi khủng hoảng, cuộc cải cách có nhiều mặt tiến bộ. Từ đó rút ra nhận xét Hồ Quý Ly là một nhân vật lịch sử có tài năng, có hoài bão, có đóng góp cho xã hội vào nửa cuối thế kỉ XIV. Hạn chế và sai lầm lớn nhất của ông là để đất nước rơi vào ách đô hộ của nhà Minh do đường lối kháng chiến sai lầm và cũng do những hạn chế trong cuộc cải cách của ông.
