Mong các bạn giúp đỡ mình . Nhớ giải hẳn ra nhé thank you very much
\(A=\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\)
\(=\frac{4064340600}{4066362660}+\frac{4064341605}{4066362660}+\frac{4070408792}{4066362660}\)
\(=3,000000742\)
\(B=\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+\frac{1}{6}+\frac{1}{7}+\frac{1}{8}+\frac{1}{9}+\frac{1}{10}+\frac{1}{11}+\frac{1}{12}+\frac{1}{13}+\frac{1}{14}+\frac{1}{15}+\frac{1}{16}+\frac{1}{17}\)
\(=1,939552523\)
vì 3,000000742 > 1,939552523. Nên A > B
mình ko chắc cho lắm nhưng nếu đúng thì k cho mình nhé !!!!!!!
