Giúp mk đi!!!!! Help me!!!!!!!!!
ta có:5A = \(\frac{5^{2011}+5}{5^{2011}+1}\) = 1+\(\frac{4}{5^{2011}+1}\)
5B=\(\frac{5^{2010}+5}{5^{2010}+1}\)=1+\(\frac{4}{5^{2010}+1}\)
\(\frac{4}{5^{2011}+1}\)<\(\frac{4}{5^{2010}+1}\)=>1+\(\frac{4}{5^{2011}+1}\)<1+\(\frac{4}{5^{2010}+1}\)
=>5A<5B=>A<B
vậy:A<B
chúc pn hok tốt ^_^
