Làm hộ mình nha !
So sánh A và B biết:
\(a.A=\)\(-\frac{1}{2016}-\frac{3}{^{11^2}}-\frac{5}{11^3}-\frac{7}{11^4}\)
\(B=-\frac{7}{11^2}-\frac{1}{2016}-\frac{5}{11^3}-\frac{3}{11^4}\)
\(b.A=\frac{2006}{2007}-\frac{2007}{2008}+\frac{2008}{2009}-\frac{2009}{2010}\)
\(B=-\frac{1}{2006.2007}-\frac{1}{2008.2009}\)
Nhờ các bạn trình bày hộ mình mình sẽ tick cho. Cảm ơn

a/\(\frac{x+7}{2003}+\frac{x+4}{2006}=\frac{x-1}{2011}+\frac{x-5}{2015}\)
b/\(\frac{x-1}{2009}+\frac{x-2}{2008}=\frac{x-3}{2007}+\frac{x-4}{2006}\)
