(1 – 1/2) . (1 – 1/3) . (1 – 1/4) . … . (1 – 1/2020)= [(2-1)/2] . [(3-1)/3] . [(4-1)/4] . … . [(2020-1)/2020]= (2/2) . (2/3) . (3/4) . … . (2019/2020)= 2/(3.4) . 3/(4.5) . … . 2019/2020= 2/2020= 1/1010#Dchibi2411# Trả lời
= [(2-1)/2] . [(3-1)/3] . [(4-1)/4] . … . [(2020-1)/2020]
= (2/2) . (2/3) . (3/4) . … . (2019/2020)
= 2/(3.4) . 3/(4.5) . … . 2019/2020
= 2/2020
= 1/1010
