\(=\dfrac{3^9\cdot3^2}{3^9}\cdot2022=3^2\cdot2022=9\cdot2022=18198\)
\(=\dfrac{3^6\cdot3^2}{3^9}\cdot2022=\dfrac{1}{3}\cdot2022=674\)
\(=\dfrac{3^9\cdot3^2}{3^9}\cdot2022=3^2\cdot2022=9\cdot2022=18198\)

\(\dfrac{2}{3}-\left|\dfrac{3}{4}\right|+\sqrt{\dfrac{25}{9}}-\left(\dfrac{2021}{2022}\right)^0\)
Tính M=\(\left(\dfrac{0,4-\dfrac{2}{9}+\dfrac{2}{11}}{1,4-\dfrac{7}{9}+\dfrac{7}{11}}-\dfrac{\dfrac{1}{3}-0,25+\dfrac{1}{5}}{1\dfrac{1}{6}-0,875+0,7}\right):\dfrac{2021}{2022}\)
Thực hiện phép tính:
a) 2021 - \(\left(\dfrac{1}{3}\right)^2\) . 32
b \(\dfrac{5}{10}\) + 9 . \(\dfrac{-3}{2}\)
c) -10 . \(\left(-\dfrac{2021}{2022}\right)^0\) + \(\left(\dfrac{2}{5}\right)^2\) : 2
So sánh:
a) \(\dfrac{-11}{12};\dfrac{17}{-18}\)
b) \(\dfrac{-14}{-21};\dfrac{-60}{-72}\)
c) \(\dfrac{2135}{13790};\dfrac{4}{3}\)
d) \(\dfrac{2022}{2021};\dfrac{10}{9}\)
e) \(\dfrac{35}{36};\dfrac{16}{17}\)
f) -1,3; -1,2
giúp mình với, mình cảm ơn
\(\dfrac{\dfrac{2022}{1}+\dfrac{2021}{2}+\dfrac{2020}{3}+...+\dfrac{1}{2022}}{\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{4}+...+\dfrac{1}{2023}}\)
Giúp mình câu này với ạ
\(5\times(\dfrac{-5}{2})^2+\dfrac{2}{15}\times\sqrt{\dfrac{9}{4}}-(-2022)^0+|-0,25|\)
\(\dfrac{2022}{2023}.\left(\dfrac{9}{13}-\dfrac{7}{11}\right)+\dfrac{2022}{2023}.\left(\dfrac{17}{13}-\dfrac{4}{17}\right)\)
Giúp mình với
a,\(\dfrac{-8}{9}\)-(\(\dfrac{6}{5}\)-\(\dfrac{8}{9}\))
b, \(\dfrac{-4}{9}\)+\(\sqrt{\dfrac{9}{16}}\)-\(\dfrac{4}{5}\).\(\dfrac{-1^2}{2}\)+25%
c,\(\dfrac{2}{3}\)+(\(\dfrac{-3}{4}\)).\(\dfrac{4}{9}\)
d,16\(\dfrac{3}{4}\) - (-\(\dfrac{6}{5}\)) - 28\(\dfrac{3}{4}\):(-\(\dfrac{6}{5}\))
a/ \(\dfrac{-3}{5}\) - x = \(\dfrac{21}{10}\)
b/ x : \(\dfrac{2}{9}\) = \(\dfrac{9}{2}\)
c/ \(\dfrac{x}{9}\) = \(\dfrac{5}{3}\)
d/ x : \(\left(\dfrac{2}{5}\right)^3\)= \(\left(\dfrac{5}{2}\right)^3\)
