3/2017 = 2016/x
=> 3.x=2017.2016
=> 3.x=4066272
=> x = 4066272 : 3
=> x = 1355424
3/2017=2016/x => 3.x=2017.2016
=> 3.x=4066272

Giai dum minh voi
MN GIUP MINH VOI DAG CAN GAP
tim x
[(6x-39)chia 7 ]
x=?
cam on ban nao da giup minh giai cau nay
a, x+1/2017 + x+2/2016 = x+3/2015 + x+4/2014
Mong cac ban giai giup minh voi
Cho A= \(\frac{2016}{2017}+\frac{2017}{2018}+\frac{2018}{2016}\)
So sanh A voi 3
so sanh 2016^2017 va 2017^2016
giup to voi!!!
Tính :
S1= 1-2+3-4+....................+2017-2018
S2= 1-4+7-10+..............+2015-2018
S3= 1+2-3-4+.....................+2015+2016-2017-2018
Giup minh voi minh dang can gap nha
ai nhanh ma dungthi minh tich cho nha
mn giup minh voi minh dag can gap
khong tinh gia tri cu the,hay so sanh 2 bieu thuc
A=123.123 va B= 121.124
C= 123.137137 va D= 137.123123
E=2015.2017 va 2016.2016
cam on mn nhieu
