A=2018/2019+2019/2020+2020/2018
B=1/3+1/4+1/5+1/6+1/7+...+1/17
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)]
A=2019^2018-1/2019^2019-1 và B=2019^2018+1/2019^2019+1 so sánh A và B
So sánh :\(\left(26^{2018}+3^{2018}\right)^{2019}\)và \(\left(26^{2019}+3^{2019}\right)^{2018}\)
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)]
Cho a/b=c/d.CMR:
(a^2018+b^2018)^2019/(c^2018+d^2018)^2019=(a^2019-b^2019)^2020/(c^2019-d^2019)^2020
MONG CÁC BẠN GIẢI SỚM, MÌNH ĐANG CẦN GẤP!!!!
so sanh \(\left(26^{2018}+3^{2018}\right)^{2019}\)
và \(\left(26^{2019}+3^{2019}\right)^{2018}\)
( 262018 + 32018 )2019 và ( 262019 + 32019 )2018
A=(252018 + 92018) 2019 ; B= (252019 + 92019) 2018. So sánh A và B. (GiẢI giúp mình vs)
