A=(1/1009+1/1010+...+1/2015+1/2016):(1/1-1/2+1/3-1/4+...+1/2015-1/2016)
tính 1/1009 X 2016 + 1 / 1010 x 2015 + ....... + 1 / 2015 x 1010 + 1/1016 x 1009
Cho V = 1/1*2+1/3*4+1/5+6+...+1/2015*2016 và Y = 1/1008+1/1009+1/1010+...+1/2016.Tính V:Y
Cho \(A=1-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+........-\frac{1}{2016};B=\frac{1}{1009}+\frac{1}{1010}+.........+\frac{1}{2016}\)
Tính \(\left(\frac{A}{B}\right)^{2015}\)
giúp mình nha !
so sánh A= 1-1/2+1/3-1/4+1/5-1/6+1/7-1/8+...+1/2015-1/2016 và B= 1/1019+1/1010+1/1011+...+1/2015+1/2016
cho hỏi : A=\(\frac{1}{1\cdot2}+\frac{1}{3\cdot4}+\frac{1}{5\cdot6}+...+\frac{1}{2015\cdot2016}\)
B=\(\frac{1}{1008}+\frac{1}{1009}+\frac{1}{1010}+...+\frac{1}{2016}\)
tính B-A
giúp vs nha,cảm ơn nhìu!

Ai giúp cảm ơn!
Tính:
A=(\(\frac{1}{2009}+\frac{1}{2010}+...+\frac{1}{2015}+\frac{1}{2016}\)):(\(\frac{1}{1}-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+...+\frac{1}{2015}-\frac{1}{2016}\))
tính a: [1-1/2*2]*[1-1/3*3]*[1-1/4*4]*[1-1/5*5]*......*[1-1/2015*2015]*[1-1/2016*2016]
