Answer 1

mình cần giải nhanh ai giải hộ mình sẽ tick

Answer 2

\(\left(1-\dfrac{1}{2}\right)\times\left(1-\dfrac{1}{3}\right)\times...\times\left(1-\dfrac{1}{100}\right)\)

\(=\dfrac{1}{2}\times\dfrac{2}{3}\times...\times\dfrac{99}{100}\)

\(=\dfrac{1\times2\times...\times99}{2\times3\times...\times100}\)

\(=\dfrac{1}{100}\)

 

Answer 3

1/2,2/4,3/4,4/5....98/99,99/100=1/100

cich cho minh di

Answer 4

Ta có: \(\left(1-\dfrac{1}{2}\right)\left(1-\dfrac{1}{3}\right)\left(1-\dfrac{1}{4}\right)\cdot...\cdot\left(1-\dfrac{1}{99}\right)\left(1-\dfrac{1}{100}\right)\)

\(=\dfrac{1}{2}\cdot\dfrac{2}{3}\cdot...\cdot\dfrac{98}{99}\cdot\dfrac{99}{100}\)

\(=\dfrac{1}{100}\)
