\(\Rightarrow\frac{x+2015}{2013}+\frac{x+2015}{2014}-\frac{x+2015}{2015}-\frac{x+2015}{2016}=0\) 0
\(\Rightarrow\left(x+2015\right)\times\left(\frac{1}{2013}+\frac{1}{2014}-\frac{1}{2015}-\frac{1}{2016}\right)\)= 0
Vì \(\frac{1}{2013}+\frac{1}{2014}-\frac{1}{2015}-\frac{1}{2016}\)khác 0
=> x + 2015 = 0
=> x = -2015
Tìm x :
\(\frac{x=2015}{2016}+\frac{x+2016}{2015}+\frac{x+2017}{2014}=-3\)
Tìm x biết : \(\frac{x+2}{2013}+\frac{x+1}{2014}=\frac{x}{2015}+\frac{x-1}{2016}\)
tìm x : \(\frac{x+2}{2015}+\frac{x+1}{2016}=\frac{x+3}{2014}+\frac{x+4}{2013}\)
cho đa thức f(x)=\(x\left(\frac{x^{2013}}{3}-\frac{x^{2014}}{5}+\frac{x^{2015}}{7}+\frac{x^2}{2}\right)-\)\(\left(\frac{x^{2014}}{3}-\frac{x^{2015}}{5}+\frac{x^{2016}}{7}+\frac{x^2}{2}\right)\).chứng minh đa thức f(x) nhận giá trị nguyên với mọi giá trị x nguyên
cho x, y,z biết \(\frac{x-1}{2016}+\frac{x-2}{2015}-\frac{x-3}{2014}=\frac{x-4}{2013}\)
Tìm x biết : \(\frac{x-1}{2016}\)+\(\frac{x-2}{2015}\)-\(\frac{x-3}{2014}\)= \(\frac{x-4}{2013}\)
Tìm x biết
\(\frac{x-1}{2015}+\frac{x-2}{2014}-\frac{x-3}{2013}=\frac{x-4}{2012}\)
\(\frac{x+1}{2013}+\frac{x+1}{2014}+\frac{x+1}{2015}=\frac{x+1}{2016}+\frac{x+1}{2017}\)
t đg cần gấp
Quản lí giúp hộ e vs !!!
