tìm x biết \(\left(1+\frac{1}{2}+\frac{1}{3}+.....+\frac{1}{2015}\right)\times x+2015=\frac{2016}{1}+\frac{2017}{2}+.....+\frac{4029}{2014}+\frac{4030}{2015}\)
Tìm x biết \(\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2015}\right)\). x + 2015 = \(\frac{2016}{1}+\frac{2017}{2}+...\frac{4029}{2014}+\frac{4030}{2015}\)
A= ( 1/2017+ 2/2016+ 3/2015+...+ 2015/3+ 2016/2+ 2017) : ( 1/2+1/3+1/4+...+1/2017+1/2018)
Thức hiện phép tính hợp lý nhất :
a) 2015 x 2016 + 2016 x 2017 - 2016 x 4030
b)3 x |-9| - 2 x 5 + 20170 : 12017
c)52 x 3 + 22 x { 13 + 5 . [30 : 2 x 5 - (34 - 30 x 2)0] }
S = 1 x 2 x 3 x 4 + 2 x 3 x 4 x5 + ... + 2015 x 2016 x 2017 x 2018
