a. So sanh 2 phan so:A= 2015/2016+2016/2017+2017/2018 va B = 2015+2016+2017/2016+2017+2018
b.1/2.4+1/4.6+........+1/(2x-2).2x = 1/8
c.Cho A = 1/4+1/9+1/16+...+1/81+1/100 . Chung minh rang : A > 65/132
d.Cho B = 12/(2 . 4 ) ^ 2 + 20/ (4 . 6) ^2 + ...........+ 388/ ( 96 . 98 ) ^ 2 + 396/ ( 98 . 100 ) ^2 .Hay so sanh B voi 1 /4
Cho tong T=2/2^1+3/2^2+4/2^3 +...+2016/2^2015+2017/2^2016.So sanh T voi 3
Cho tong T=2/2^1+3/2^2+4/2^3 +...+2016/2^2015+2017/2^2016.So sanh T voi 3
ai trả lời được mình tik 3 nick luôn
so sanh A voi 1 biet A= 2^2019-(2^2018+2^2017+...+2^1+2^0)
A=(1+1/2015)×(1+1/2015^2)+...+(1+1/2015^2016)
So sanh voi B=2015^2-1/2014^2-1
so sanh
A = 2016^2 va B = 2017 . 2015
cho A = 1+2+22+23+...+22014+22015
a thu gon A
b so sanh A voi 9x22013
so sanh tong s=1/2+2/2^2+......+2015/2^2015 voi 2
