Question

Tính tích sau P=(1-1\2)(1-1\3)(1-1\4)(1-1\5)...(1-1\99)(1-1\100)

Answer 1

P=(1-1/2)(1-1/3)(1-1/4)....(1-1/100)

P=1/2.2/3.3/4.......99/100

P=(1.2.3....99)/(2.3.4...100)=1/100

Vậy P=1/100

Answer 2

p=1/100

Answer 3

\(P=\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)...\left(1-\frac{1}{99}\right)\left(1-\frac{1}{100}\right)\)

\(=\frac{1}{2}.\frac{2}{3}.\frac{3}{4}.....\frac{98}{99}.\frac{99}{100}\)

\(\Leftrightarrow P=\frac{1}{100}\)

Answer 4

2^3_bbnvbn

Answer 5

P=\(\frac{1}{2}.\frac{2}{3}.\frac{3}{4}...\frac{99}{100}\)​

P=\(\frac{1}{100}\)

Answer 6

1/100 bn nhé
