Question

\(\left(1-\frac{1}{2}\right).\left(1-\frac{1}{3}\right)......\left(1-\frac{1}{2012}\right)\)

Answer 1

\(\left(1-\frac{1}{2}\right).\left(1-\frac{1}{3}\right)....\left(1-\frac{1}{2012}\right)\)

\(=\frac{1}{2}.\frac{2}{3}....\frac{2011}{2012}\)

\(=\frac{1.2....2011}{2.3....2012}\)

\(=\frac{1}{2012}\)

Answer 2

Ta co : (1 - 1/2) . (1 - 1/3) . (1 - 1/4) ...... (1 - 1/2011) . (1 - 1/2012)

       =  1/2 . 2/3 . 2/4 ...... 2010/2011 . 2011/2012

       = 1/2012
