Question

A= (1-1/2010) x (1- 2/2010) x (1- 3/2010) x.... x( 1- 2011/2010) =?

Answer 1

Vì ta có 1 - 1/2010 = 0/2010 = 0 nên suy ra biểu thức A = 0

Answer 2

A=\(\left(1-\frac{1}{2010}\right).\left(1-\frac{2}{2010}\right)...\left(1-\frac{2010}{2010}\right)\left(1-\frac{2011}{2010}\right)\)

A=\(\frac{2009}{2010}.\frac{2008}{2010}...0.\frac{-1}{2010}\)

A=0
