tính bằng cách thuận tiện nhất: 26/7 x 11/3 - 26/7 x 2/3 - 6/3 x 26/7

Answer 1

  \(\dfrac{26}{7}\) x \(\dfrac{11}{3}-\dfrac{26}{7}\) x \(\dfrac{2}{3}-\dfrac{6}{3}\) x \(\dfrac{26}{7}\)

\(=\dfrac{26}{7}\) x \(\left(\dfrac{11}{3}-\dfrac{2}{3}-\dfrac{6}{3}\right)\)

\(=\dfrac{26}{7}\) x \(\dfrac{3}{3}\)

\(=\dfrac{26}{7}\) x \(1=\dfrac{26}{7}\)

 

Answer 2

26/7 x 11/3 - 26/7 x 2/3 - 6/3 x 26/7
