Cho a/b=c/d C/M (a+b)/c+d)2016=a2016+b2016/c2016+d2016
cho\(\frac{a}{b+c+d}=\frac{b}{c+d+a}=\frac{c}{d+a+b}=\frac{d}{a+b+c}\)
tính A=\(\frac{a^{2016}}{b^{2016}}+\frac{b^{2016}}{c^{2016}}+\frac{c^{2016}}{d^{2016}}+\frac{d^{2016}}{a^{2016}}\)
((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 .Chứng minh rằng
a) a2016 +c2016/ b2016+ d2016= (a-c)2016/ b-d) 2016
A=a^2016+b^2016+c^2016+d^2016/(a+b+c+d)^2016
Biet ac=b^2 : ac=d^2
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 a/b=c/d Chứng minh rằng
a) a+2c/b+2d= a-3c/b-3d
b) (a-c)4/(b-d)4
c) a2016+c2016/b2016= (a-c)2016/(b-d )2016
CHO CÁC SỐ DƯƠNG a,b,c khác d và \(\frac{a}{b}=\frac{c}{d}\)
CMR. \(\frac{\left(a^{2016}+b^{2016}\right)^{2017}}{\left(c^{2016}+d^{2016}\right)^{2017}}=\frac{\left(a^{2017}-b^{2017}\right)^{2016}}{\left(c^{2017}-b^{2017}\right)^{2016}}\)
