\(A=\left(1-\frac{1}{2016}\right).\left(1-\frac{2}{2016}\right).....\left(1-\frac{2017}{2016}\right)\)
\(A=\left(1-\frac{1}{2016}\right).....\left(1-\frac{2016}{2016}\right).\left(1-\frac{2017}{2016}\right)\)
\(A=\left(1-\frac{1}{2016}\right)......0.\left(1-\frac{2017}{2016}\right)\)
\(A=0\)
(1/2+2015/2016+2016/2017+1)(2015/2016+2016/2017+7/22)-(1/2+2015/2016+2016/2017)(2015/2016+2016/2017+7/22+1)
So sanh A va B biet
A=2017^100/1+2017+2017^2+2017^3+.....+2017^100
B=2016^100/1+2016+2016^2+2016^3+.....+2016^100
Tính
(1/2 + 2015/2016 + 2016/2017 + 1)(2015/2016 + 2016/2017 + 7/22) - (1/2 + 2015/2016 + 2016/2017)(2015/2016 + 2016/2017 + 7/22 + 1)
Giúp mk với
(1/2+2015/2016+2016/2017+1)(2015/2016+2016/2017+7/22)-(1/2+2015/2016+2016/2017)(2015/2016+2016/2017+7/22+1)
Tính tích:
\(A=\left(1-\frac{1}{2016}\right)\left(1-\frac{2}{2016}\right)\left(1-\frac{3}{2016}\right)...\left(1-\frac{2017}{2016}\right)\)
giải bài toán a=(1-1/2016)x(1-2/2016)x(1-3/2016)x...x(1-2017/2016)
(1+2015/2016+2016/2017+1/2).(2015/2016+2016/2017+7/22)-(2015/2016+2016/2017+1/2).(2015/2016+2016/2017+7/22+1)
tính tổng trên
( trình bày cách tính
K-2016=1+ (1+2)+(1+2+3)+….+(1+2+3+…+2017)/2017*1+2016*2+2015*3+…+2*2016+1*2017
tìm K
(1/2+2015/2016+216/2017+1)(2015/2016+2016/2017+7/22)-(1/2+2015+2016)(2015/2016+2016/2017+7/22+1)
