Bài mấy ạ?

C nhé

Câu A nhé

Ta có: 25 x 165 x 4 = ( 25 x 4 ) x 165 = 100 x 165 = 16500

Ta có :

\(A=\dfrac{1^2}{1.2}.\dfrac{2^2}{2.3}.\dfrac{3^2}{3.4}.\dfrac{4^2}{4.5}.\dfrac{5^2}{5.6}\)\(=\dfrac{1.1.2.2.3.3.4.4.5.5}{1.2.2.3.3.4.4.5.5.6}\)

\(=\dfrac{1.2.3.4.5}{1.2.3.4.5}.\dfrac{1.2.3.4.5}{2.3.4.5.6}=1.\dfrac{1}{6}=\dfrac{1}{6}\)

Ko hiểu chỗ nào hỏi mình nha
