Bài 1: Cho đoạn văn sau:

Có lẽ bắt đầu từ những đêm sương sa thì bóng tối đã hơi cứng và sáng ngày ra thì trông thấy màu trời có vàng hơn mọi khi. Lúa chín dưới đồng vàng xuộm lại. Nắng nhạt ngả màu vàng hoe. Trong vườn, lắc lư những chùm quả xoan vàng lịm, không trông thấy cuống, như những chuỗi tràng hạt bồ đề treo lơ lửng. Từng chiếc lá mít vàng sẫm. Tàu đu đủ, chiếc lá sắn héo lại mở năm cánh vàng tươi. Vườn chuối quả chín vàng đốm. Nắng vườn chuối đương có gió lẫn với lá vàng, như những đuôi, vạt áo nắng. Bụi mía vàng xọng, từng đốt ngần phấn trắng. Dưới sân, rơm và thóc vàng giòn. Quanh đó, con gà, con chó cũng vàng mượt. Mái nhà phủ một màu rơm vàng mới. Lác đác cây lựu có mấy chiếc lá đỏ... Tất cả đượm một màu vàng trù phú, đầm ấm lạ lùng. Không còn có cảm giác héo tàn, hanh hao lúc sắp bước vào mùa đông. Hơi thở của đất trời, mặt nước thơm thơm, nhè nhẹ."

Đặt \(A=\left|x-3\right|+\left|x-6\right|-2\)

\(\Leftrightarrow A=\left|x-3\right|+\left|-\left(x-6\right)\right|-2\)

\(\Leftrightarrow A=\left|x-3\right|+\left|6-x\right|-2\)

Áp dụng BĐT \(\left|a\right|+\left|b\right|\ge\left|a+b\right|\)ta được :

\(A=\left|x-3\right|+\left|6-x\right|-2\ge\left|x-3+6-x\right|-2=\left|3\right|-2=3-2=1\)

Đẳng thức xảy ra khi \(ab\ge0\)

\(\Leftrightarrow\left(x-3\right)\left(6-x\right)\ge0\)

\(\Leftrightarrow3\le x\le6\)

Vậy AMin  = 1 khi \(3\le x\le6\)

Gọi chiều dài a ; chiều rộng b (m)

Ta có a = 2 x b

=> S ban đầu = a x b = 2 x b x b 

=> S thay đổi = (a - 2)(b + 2) = a x b + 2 x a - 2 x b - 4 = a x b + 2 x (a - b) - 4 = 2 x b x b + 2 x b - 4

Lại  có : S thay đổi - S ban đầu = 60 m 

<=> 2 x b x b + 2 x b - 4 - 2 x b x b = 60

=> 2 x b - 4 = 60

=> 2 x b = 64

=> b = 32

=> a = 64

=> S ban đầu : 32 x 64 = 2048

Để |M| đạt giá trị nhỏ nhất  ta đặt dấu dương đến dấu âm  trước các hạng tử so le nhau bắt đầu từ số 2  

<=> M = 1 + (2 - 3) + (4 - 5) + .... + (2016 - 2017) [808 cặp]

         = 1 + (-1) + (-1) + .... + (-1)  (808 số hạng (-1)

Ta thấy 20162019 4; 82018 4. Đặt 20162019 = 4k; 82018 = 4h (k,hN)

.

Ta có: 2A=74k34h=2401k81h=...1(...1)=...0

Từ đó 2A chia hết cho 5.

Mà A là số tự nhiên và (2; 5) = 1 nên A chia hết cho 5.

a) Xét tam giác ABD và tam giác HBD có : 
               góc ABD = góc HBD (BD là tia pg)
             góc BAD = góc BHD=90 độ (gt)
                  BD là cạnh chung
=> Tam giác ABD  = Tam giác HBD (CH-GN)
=> AD = DH ( 2 cạnh tương ứng )

b) Xét tam giác DHC có : 
Góc DHC = 90 độ => DC là cạnh huyền => DC > DH
Ta lại có : AD=DH ( cm ở câu a )
=> DC>AD
