[Nhi Đỗ]

\(E=\left[\dfrac{1919}{2121}-\dfrac{54}{99}+\left(\dfrac{2456}{3799}\right)^5\right]\cdot\left(\dfrac{1}{2}-\dfrac{1}{3}-\dfrac{1}{6}\right)\)

Answer 1

[Nguyễn T.Kiều Linh]

\(E=\left[\dfrac{1919}{2121}-\dfrac{54}{99}+\left(\dfrac{2456}{3799}\right)^5\right].\left(\dfrac{1}{2}-\dfrac{1}{3}-\dfrac{1}{6}\right)\)

E \(=\left[\dfrac{1919}{2121}-\dfrac{54}{99}+\left(\dfrac{2456}{3799}\right)^5\right].0\)

E = 0

Vậy E = 0
