Rút gọn A= (1/2+ 1/3+ 1/4+.....+ 1/2013)/ ( 2012+ 2012/2 + 2011/ 3+....+ 1/ 2013)
Rút gọn (1/2+1/3+1/4+...+1/2013) : (2012+2012/2+2011/3+....+1/2013)
Ai giải được
Rút gọn \(A=\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+...+\frac{1}{2013}}\)ta đc A= ?
Rút gọn A=\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+...+\frac{1}{2013}}\)Ta được A=
Rút gọn A=\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+...+\frac{1}{2013}}\)Ta được A=...
Rút Gọn A= 1/2+1/3+1/4+...+1/2013 2012+2012/2+2011/3+....+1/2013
Rút gọn biểu thức sau:
A=\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+....+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+....+\frac{1}{2013}}\)
Rút gọn \(\frac{\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+...+\frac{1}{2013}}\)
Rút gọn A = \(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2013}}{2012+\frac{2012}{2}+\frac{2011}{3}+...+\frac{1}{2013}}\)
ta được A = .......
