Cho a/b=c/d C/M (a+b)/c+d)2016=a2016+b2016/c2016+d2016
A=a^2016+b^2016+c^2016+d^2016/(a+b+c+d)^2016
Biet ac=b^2 : ac=d^2
cho a/b =c/d .Chứng minh rằng
a) a2016 +c2016/ b2016+ d2016= (a-c)2016/ b-d) 2016
Cho \(\frac{a^{2106}+b^{2016}}{c^{2016}+d^{2016}}\)= \(\frac{a^{2016}-b^{2016}}{c^{2016}-d^{2016}}\)Chứng minh rằng \(\frac{a}{b}\)= \(\pm\frac{c}{d}\)
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
