Question

[ 1+ 1/2] . [ 1+ 1/3]. [ 1+1/4] .[1+ 1/5] . [ 1+1/6] . [ 1+1/7] . [ 1+ 1/8]

ai dung minh tick cho nhe minh can gap

Answer 1

\(\left(1+\frac{1}{2}\right)\times\left(1+\frac{1}{3}\right)\times\left(1+\frac{1}{4}\right)\times...\times\left(1+\frac{1}{8}\right)\)

\(=\frac{3}{2}\times\frac{4}{3}\times\frac{5}{4}\times...\times\frac{9}{8}\)

\(=\frac{9}{2}\)

Answer 2

= [ 2/2 + 1/2 ] . [ 3/3 + 1/3 ] . [ 4/4 + 1/4 ] . [ 5/5 + 1/5 ] . [ 6/6 +1/6 ] . [ 7/7 + 1/7 ] . [ 8/8 + 1/8 ]

=      3/2 . 4/3 . 5/4 . 6/5 .7/6 .8/7. 9/8

=      9/2

Nhớ k cho mình nhé

Answer 3

\(\left(1+\frac{1}{2}\right).\left(1+\frac{1}{3}\right).\left(1+\frac{1}{4}\right).\left(1+\frac{1}{5}\right).\left(1+\frac{1}{6}\right).\left(1+\frac{1}{7}\right).\left(1+\frac{1}{8}\right)\)

\(=\frac{3}{2}.\frac{4}{3}.\frac{5}{4}.\frac{6}{5}.\frac{7}{6}.\frac{8}{7}.\frac{9}{8}=\frac{9}{2}\)
