giải hộ vs :((( tỉ mỉ nha !
Lm đúng mk tick cho
cho \(\frac{x^4}{a}+\frac{y^4}{b}=\frac{1}{\left(a+b\right)},x^2+y^2=2\)
CMR: \(\frac{x^{2016}}{a^{1008}}+\frac{y^{2016}}{b^{1008}}=\frac{2}{\left(a+b\right)^{1008}}\)
Cho S=\(1-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+.........+\frac{1}{2013}-\frac{1}{2014}+\frac{1}{2015}\)
P=\(\frac{1}{1008}+\frac{1}{1009}+\frac{1}{1010}+...........+\frac{1}{2014}+\frac{1}{2015}\)

Chứng minh rằng : \(B=1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+....+\frac{1}{2^{2016}-2}+\frac{1}{2^{2016}-1}>1008\)
Cho a,b,c,d\(\in\)N* ,a2+c2=1 và \(\frac{a^4}{b}+\frac{c^4}{d}=\frac{1}{b+d}\)CMR:
\(\frac{a^{2016}}{b^{1008}}+\frac{c^{2016}}{d^{1008}}=\frac{2}{\left(b+d\right)^{1008}}\)
Tính \(\left(S-P\right)^{2015}+\left(S+P\right)^{2016}\)
\(S=1-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+......+\frac{1}{2003}-\frac{1}{2004}+\frac{1}{2005}\)
\(P=\frac{1}{1008}+\frac{1}{1009}+.........+\frac{1}{2014}+\frac{1}{2015}\)
