Question

thực hiện phep tinh :

(1 -  1/2 ) x ( 1 - 1/3 ) x ( 1 - 1/4 ) x (1- 1/5 ) 

giup mik vơi nha

Answer 1

\(\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)\left(1-\frac{1}{4}\right)\left(1-\frac{1}{5}\right)\)

\(=\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\)

\(=\frac{1}{5}\)

Answer 2

\(\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)\left(1-\frac{1}{4}\right)\left(1-\frac{1}{5}\right)\)

\(=\frac{1}{2}.\frac{2}{3}.\frac{3}{4}.\frac{4}{5}=\frac{1}{5}\)

Answer 3

\(\left(1-\frac{1}{2}\right)\text{ x }\left(1-\frac{1}{3}\right)\text{ x }\left(1-\frac{1}{4}\right)\text{ x }\left(1-\frac{1}{5}\right)\)

\(=\frac{1}{2}\text{ }\text{ x }\frac{2}{3}\text{ x }\frac{3}{4}\text{ x }\frac{4}{5}\)

\(=\frac{1}{5}\)

Answer 4

( 1 - 1/2 ) x ( 1 - 1/3 ) x ( 1 - 1/4 ) x ( 1 - 1/5 ) 

= \(\frac{1}{2}.\frac{2}{2}.\frac{3}{4}.\frac{4}{5}=\frac{1}{5}\)
