Tính :A= [(2018/1)+(2017/2)+(2016/3)+(2015/4)+...+(4/2015)+(3/2016)+(2/2017)+(1/2018)]/[(2019/2)+(2019/3)+(2019/4)+(2019/5)+...+(2019/2015)+(2019/2016)+(2019/2017)+(2019/2018)+(2019/2019)]
Tính :A= [(2018/1)+(2017/2)+(2016/3)+(2015/4)+...+(4/2015)+(3/2016)+(2/2017)+(1/2018)]/[(2019/1)+(2019/2)+(2019/3)+(2019/4)+...+(2019/2015)+(2019/2016)+(2019/2017)+(2019/2018)+(2019/2019)]
so sánh A và B A=2016/2017-2017/2018+2018/2019-2019/2020 B=-1/2016-2017 - 1/2018-2019
Tính:
A=2019/2018 - 2018/2017 + 2017/2016 - 2016/2015
B=1/2019 - 1/2018 + 1/2017 - 1/2016
C=1/2017 - 1/2016 + 1/2015 - 1/2014
A = \(\frac{2016}{2017}+\frac{2017}{2018}+\frac{2018}{2019}\)và B = \(\frac{2016+2017+2018}{2017+2018+2019}\)
Tính tỉ số A/B biết:
A=1/2 + 1/3 + 1/4 + ... + 1/2017 + 1/2018 + 1/2019
B=2018/1 + 2017/2 + 2016/3 + ... + 2/2017 + 1/2018
tính P=(1/2+1/3+1/4+........+1/2019)/(2018/1+2017/2+2016/3+....+1/2018)
tính P=(1/2+1/3+1/4+........+1/2019)/(2018/1+2017/2+2016/3+....+1/2018)
