Question

Giá trị \(x\) thoả mãn \(\dfrac{x}{2}+\dfrac{x}{4}+\dfrac{x}{2016}=\dfrac{x}{3}+\dfrac{x}{5}+\dfrac{x}{2017}\) là \(x\)=

Answer 1

\(\dfrac{x}{2}+\dfrac{x}{4}+\dfrac{x}{2016}=\dfrac{x}{3}+\dfrac{x}{5}+\dfrac{x}{2017}\)

\(\Rightarrow x.\left(\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{2016}\right)=x.\left(\dfrac{1}{3}+\dfrac{1}{5}+\dfrac{1}{2017}\right)\)

Vì \(\dfrac{1}{2}>\dfrac{1}{3};\dfrac{1}{4}>\dfrac{1}{5};\dfrac{1}{2016}>\dfrac{1}{2017}\)

\(\Rightarrow\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{2016}>\dfrac{1}{3}+\dfrac{1}{5}+\dfrac{1}{2017}\)

\(\Rightarrow x=0\)
