Giup minh trinh bay cach cach giai voi nhe

Ko hieu vao phan"Doc them"

so sanh A va B bit

A=\(\frac{1}{3}+\frac{1}{4}+...+\frac{1}{17}\)

B=\(\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\)

Tinh :

A=\(\left(1+\frac{1}{1.3}\right)\left(1+\frac{1}{2.4}\right)\left(1+\frac{1}{3.5}\right)....\left(1+\frac{1}{2014.1016}\right)\)

Giup minh trinh bay ca cach lam nua nha!

Ai chua doc het de va ko hieu thi vao phan "Doc them" se ro

Thanks

Ai chua doc het de va ko hieu thi vao phan "Doc them" se ro

Thanks

So sanh  :

A=\(\frac{2010}{2011}\)+ \(\frac{2011}{2012}+\frac{2012}{2013}\)va B=\(\frac{2010+2011+2012}{2011+2012+2012}\)

C = 333⁴⁴⁴ va 444³³³

1.So sánh A và B:

\(A=\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\)và \(B=\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+..........+\frac{1}{17}\)

Tinh:

\(B=\frac{\frac{1}{7}+\frac{1}{23}-\frac{1}{1009}}{\frac{1}{7}+\frac{1}{23}-\frac{1}{1009}+\frac{1}{7}.\frac{1}{23}.\frac{1}{1009}}\)

Trinh bay cach lam nua nhe

Co gi ko hieu thi vao phan doc them

  bài 1 :a) Tính M:\(\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)

          b) So sánh A và B biết A =\(\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\);;; B =\(\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+....+\frac{1}{17}\)

So sánh A và B biết   \(A=\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\)    và    \(B=\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+...+\frac{1}{17}\)
