\(\dfrac{3}{17}\) .\(\dfrac{6}{29}\) - \(\dfrac{3}{17}\).\(\dfrac{35}{29}\) + 2022\(\dfrac{3}{17}\)
= (\(\dfrac{3}{17}\).\(\dfrac{6}{29}\) - \(\dfrac{3}{17}\).\(\dfrac{35}{29}\)) + 2022 + \(\dfrac{3}{17}\)
= \(\dfrac{3}{17}\).(\(\dfrac{6}{29}\) - \(\dfrac{35}{29}\)) + 2022 + \(\dfrac{3}{17}\)
= \(\dfrac{3}{17}\).(-1) + 2022 + \(\dfrac{3}{17}\)
= (- \(\dfrac{3}{17}\) + \(\dfrac{3}{17}\)) + 2022
= 0 + 2022
= 2022
b; \(\dfrac{5}{6}\) - (\(\dfrac{1}{3}\) + \(\dfrac{1}{2}\)).20%
= \(\dfrac{5}{6}\) - \(\dfrac{5}{6}\).\(\dfrac{1}{5}\)
= \(\dfrac{5}{6}-\dfrac{1}{6}\)
= \(\dfrac{4}{6}\)
= \(\dfrac{2}{3}\)
A)17/5.-31/125.1/2.10/17.-1/2 mũ 3
=(17/5.10/17).(1/2.-1/6).-31/125
=2.(-1/12).(-31/125)
=-1/6.(-31/125)
=31/125
B)(11/4.-5/9.4/9.11/4).8/33
=(11/4.(-5/9.4/9)).8/33
=(11/4.(-1)).8/33
=(-11/4).8/33
=-2/3
C)(135/21 +45/123 - 55/434).(-5/12 + 1/4 + 1/6
=(135/21 +45/123 - 55/434).(5/12+3/12+2/12)
=(135/21 +45/123 - 55/434).0
= 0
D) 132/111. (1 /2 + 1/3 + 7/6)
=12.(3/6+2/6+7/6)
= 12.7/3
= 28
E)1/5.1/6 + 1/6.1/7 + 1/7.1/8 + 1/8 . 1/9 + 1/9.9/10
=1/5.6+1/6.7+1/7.8+1/8.9+(1/9.9/10)
=1/5-1/6+1/6-1/7+1/7-1/8+1/8-1/9+1/10
=1/5-1/10
= 1/10
Mình ko biết làm câu F thông cảm nhé
Sai thì bình luận cho mình biết với nhé
a: \(=\dfrac{-3}{7}+\dfrac{15}{26}-\dfrac{2}{13}+\dfrac{3}{7}=\dfrac{15}{26}-\dfrac{4}{26}=\dfrac{11}{26}\)
b: \(=\dfrac{6}{7}+\dfrac{2}{9}-\dfrac{10}{7}-5=\dfrac{-4}{7}-5+\dfrac{2}{9}=-\dfrac{337}{63}\)
c: \(=-\dfrac{11}{23}\left(\dfrac{6}{7}+\dfrac{8}{7}\right)-\dfrac{1}{23}=\dfrac{-22}{23}-\dfrac{1}{23}=-1\)
