cho\(\frac{a}{b+c+d}=\frac{b}{c+d+a}=\frac{c}{d+a+b}=\frac{d}{a+b+c}\)
tính A=\(\frac{a^{2016}}{b^{2016}}+\frac{b^{2016}}{c^{2016}}+\frac{c^{2016}}{d^{2016}}+\frac{d^{2016}}{a^{2016}}\)
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 :
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
((a-b)/(c-d))^2016=(a^2016+b^2016)/(c^2016+d^2016)
K=a^2016+b^2016+c^2016+d^2016:(a+b+c+d)^2016
Cho a/b=c/d C/M (a+b)/c+d)2016=a2016+b2016/c2016+d2016
cho\(\frac{a}{b}\)=\(\frac{c}{d}\)
CMR: \(\frac{ac}{bd}\)=\(\frac{2016.a^2+2017.c^2}{2016.b^2+2017.d^2}\)
CMR nếu a/b=c/d thì a^2016+3b^2016/c^2016+3d^2016=(a^2+2b^2/c^2+2d^2)^1008
CMR nếu a/b=c/d thì a^2016+3b^2016/c^2016+3d^2016=(a^2+2b^2/c^2+2d^2)^1008
cho a/b =c/d .Chứng minh rằng
a) a2016 +c2016/ b2016+ d2016= (a-c)2016/ b-d) 2016
