Theo đề bài
\(\overline{abc,d}-\overline{a,bcd}=583,704\)
\(\Rightarrow100x\overline{a,bcd}-\overline{a,bcd}=583,704\)
\(\Rightarrow99x\overline{a,bcd}=583,704\Rightarrow\overline{a,bcd}=583,704:99=5,896\Rightarrow\overline{abc,d}=589,6\)
Tổng hai số là
\(\overline{589,6}+5,896=595,496\)
tim x biet;
[1/3x5+1/5x7+1/7x9+...1/9x11]nhan x =8/11. giup minh nhe cac ban dep trai dep gai nhe.
\(\left(\frac{1}{3x5}+\frac{1}{5x7}+\frac{1}{7x9}+\frac{1}{9x11}\right)xX=\frac{8}{11}\)
\(\Rightarrow\left(\frac{2}{3x5}+\frac{2}{5x7}+\frac{2}{7x9}+\frac{2}{9x11}\right)xX=\frac{16}{11}\)
\(\Rightarrow\left(\frac{5-3}{3x5}+\frac{7-5}{5x7}+\frac{9-7}{7x9}+\frac{11-9}{9x11}\right)xX=\frac{16}{11}\)
\(\Rightarrow\left(\frac{1}{3}-\frac{1}{5}+\frac{1}{5}-\frac{1}{7}+\frac{1}{7}-\frac{1}{9}+\frac{1}{9}-\frac{1}{11}\right)xX=\frac{16}{11}\)
\(\Rightarrow\left(\frac{1}{3}-\frac{1}{11}\right)xX=\frac{16}{11}\Rightarrow\frac{8}{33}xX=\frac{16}{11}\)
\(\Rightarrow X=\frac{16}{11}:\frac{8}{33}=\frac{16}{11}x\frac{33}{8}=6\)
