b mik ko chơi nhưng em mình chơi

1/2+3/5+1/9+1/127+7/18+4/35+2/7

=(1/2+1/9)+(3/5+2/7)+1/127+7/18+4/35

=11/18+31/35+1/127+7/18+4/35

=(11/18+7/18)+(31/35+4/35)+1/127

=1+1+1/127

=2+1/127

=2\(\frac{1}{127}\)

\(\left(\dfrac{13}{2020}+\dfrac{23}{2021}+\dfrac{33}{2022}\right).\left(\dfrac{1}{2}-\dfrac{1}{3}-\dfrac{1}{6}\right)\)

= \(\left(\dfrac{13}{2020}+\dfrac{23}{2021}+\dfrac{33}{2022}\right).\left(\dfrac{3}{6}-\dfrac{2}{6}-\dfrac{1}{6}\right)\)

= \(\left(\dfrac{13}{2020}+\dfrac{23}{2021}+\dfrac{33}{2022}\right).0\)

=\(0\)

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

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

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

Nhớ k cho mình nhé

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