Tính nhanh
A= 2016 x 2017 +4034 / 2018 x 2019 - 4036
Giai pt:
\(\left(1+\dfrac{1}{2}+\dfrac{1}{3}+...+\dfrac{1}{2015}+\dfrac{1}{2016}+\dfrac{1}{2017}\right).3x=1+\dfrac{2019}{2}+\dfrac{2020}{3}+...+\dfrac{4033}{2016}+\dfrac{4034}{2017}\)
Cho các số a,b,c,d khác 0. Tính
T= x^2017 + y^2017+z^2017+t^2017
Biết x,y,z,t thỏa mãn :
x^2016+y^2016+z^2016+t^2016/a^2+b^2+c^2+d^2=x^2016/a^2+y^2016/b^2+z^2016/c^2+t^2016/d^2
2015/4034 < 1/22+1/32+1/42+...+1/20162 < 2015/2016
1/2.3 +1/3.4+...+1/2016.2017 < 1/2^2+1/3^2+...+1/2016^2
1/2 -1/3+1/3 -1/4+...+1/2016-1/2017 < 1/2^2+1/3^2+...+1/2016^2
1/2-1/2017 < 1/2^2+1/3^2+...+1/2016^2
=> 2015/4034 < 1/2^2+1/3^2+...+1/2016^2
tương tự
1/2^2+1/3^2+...+1/2016^2 < 1/1.2 +1/2.3+...+1/2015.2016
1/2^2+1/3^2+...+1/2016^2 < 1- 1/2+1/2 -1/3+...+1/2015- 1/2016
1/2^2+1/3^2+...+1/2016^2 < 1-1/2016
1/2^2+1/3^2+...+1/2016^2 < 2015/2016

Cho các số a,b,c,d khác 0. Tính \(T=x^{2017}+y^{2017}+z^{2017}+t^{2017}\)
Biết x,y,z,t thỏa mãn: \(\dfrac{x^{2016}+y^{2016}+z^{2016}+t^{2016}}{a^2+b^2+c^2+d^2}=\dfrac{x^{2016}}{a^2}+\dfrac{y^{2016}}{b^2}+\dfrac{z^{2016}}{c^2}+\dfrac{t^{2016}}{d^2}\)
x-3/2016+x-2/2017=x-2017/2+x-2016/3
Tìm x, biết:
(20165:20164-1/2-20178:20176)-x/2016= 2017/2016.
