So sanh A=2018/-2017 va B=-2019/2019
so sanh a va b
A = 2017^ 10 x 2017 ^ 9
B= 2018^ 10
So sanh a va b ma khong tinh gia tri cua a va b
A=2016×2018 ; B = 2017× 2017
Ai lam đung minh se tich cho😙😙😙😙😙😙
Cho A = 1 + 2 + 2^2 + 2 ^ 3 + ... + 2 ^2017
va B -= 2^2018 - 1
So sanh A va B
giai ra giu mk nha
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
so sanh a va b biet
A=\(\frac{1020^{1021}+5}{1020^{1022}+1}\)
B=\(\frac{2017^{2018}+3}{2017^{2019}+1}\)
giup minh lam nhe
So sanh :\(\frac{2017}{2018}+\frac{2018}{2019}va\frac{2015}{2016}+\frac{2016}{2017}\)
cho A = 20172017+2/20172017-1 va B= 20172017/20172017-3
So sanh A va B
Cho A=1.2+2.3+3.4+4.5+............+2017.2018 va B=2018 mu3/3 So sanh A va B
