\(\dfrac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}\)

\(\dfrac{2-3.256}{128-7}\)

\(\dfrac{-766}{121}\)

tick cho mink nha bạn

42 là 54 cũng được mà bạn ơi

6 bạn ạ

mink không chép lại đề nha bạn

\(\dfrac{28}{15}\).\(\dfrac{3}{4}\)\(-\)\(\left(\dfrac{104}{195}+\dfrac{1}{4}\right).\dfrac{24}{47}-\dfrac{51}{13}:3\)

\(\dfrac{7}{5}\)\(-\dfrac{23}{60}\).\(\dfrac{24}{47}\)\(-\dfrac{17}{13}\)

\(\dfrac{7}{5}\)\(-\dfrac{46}{235}\)\(-\dfrac{17}{13}\)

\(\dfrac{283}{235}\)\(-\dfrac{17}{13}\)

= (đến đây bạn tự tính ra kết quả nhé)

tick nha bạn

Ư(123)là 1;3;41;123

\(4\dfrac{1}{3}.\left(\dfrac{1}{6}-\dfrac{1}{2}\right)\le x\le\dfrac{2}{3}.\left(\dfrac{1}{3}-\dfrac{1}{2}-\dfrac{3}{4}\right)\)

\(\dfrac{13}{3}.\dfrac{-1}{3}\le x\le\dfrac{2}{3}.\dfrac{-11}{12}\)

\(\dfrac{-13}{9}\)\(\le x\le\)\(\dfrac{-11}{18}\)

\(\dfrac{-26}{18}\)\(\le x\le\dfrac{-11}{18}\)

\(\Rightarrow x\in\left\{\dfrac{-12}{18};\dfrac{-13}{18};\dfrac{-14}{18};\dfrac{-15}{18};...;\dfrac{-24}{18};\dfrac{-25}{18}\right\}\)Tick hộ mình nha bạn
