Question

Giúp với ạ

Answer 1

<=> \(M=\dfrac{6.\left(\dfrac{1}{1017}+\dfrac{1}{1018}+\dfrac{1}{1019}\right)}{1:1017+\dfrac{1017}{1018}:1017+\dfrac{1017}{1019}:1017}\)

<=> \(M=\dfrac{6.\left(\dfrac{1}{1017}+\dfrac{1}{1018}+\dfrac{1}{1019}\right)}{\dfrac{1}{1017}+\dfrac{1}{1018}+\dfrac{1}{1019}}\)

<=> \(M=6\)

Khong hiểu chỗ nào e hỏi lại nhé
