Cho da thuc f(x)=x^99-2014.x^98+2014.x97-2014.x^96+.....-2014.x^2+2014.x-1.Tinh f(2013)?
Tìm x
|(x + 2002)(x - 2013)| + |(x - 2013)(x - 2014)| = 0
tính giá trị biểu thức:
A= x^21 - 2014.x^20 + 2014.x^19 - 2014.x^18 + 2014.x^17 - 2014.x^16 +........- 2014.x^2 +2014.x -1 (tại x = 2013)
tim x ;
(1+1/2+1/3+...+1/2013).x+2013=2014/1+2015/2+...+4026/2013
Tìm x , biết : (1+1/2+1/3+...+1/2013).x+2013=2014/1+2015/2+...+4026/2013
|x - 2012| + |x - 2013| = 2014
