\(\dfrac{11}{24}-\dfrac{5}{41}+\dfrac{13}{24}+0.5-\dfrac{36}{41}\) nhớ cho cách lm nhá
Thực hiện phép tính (Tính hợp lý nếu có thể).
a) $\dfrac{11}{24}-\dfrac{5}{41}+\dfrac{13}{24}+0,5-\dfrac{36}{41}$.
b) $\dfrac{1}{2} \cdot \dfrac{3}{4}+\dfrac{1}{2} \cdot \dfrac{1}{4}+\dfrac{1}{2}$.
c) $\Big(\dfrac{-3}{4}\Big)^2:\Big(\dfrac{-1}{4}\Big)^2+9 \cdot\Big(\dfrac{-1}{9}\Big)+\Big( \dfrac{-3}{2} \Big)$.
d) $\sqrt{0,25} \cdot(-3)^3-\sqrt{\dfrac{1}{81}}:\Big(\dfrac{-1}{3}\Big)^3$.
\(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\)
\(\left(\dfrac{15}{4}-5x\right)\cdot\left(9x^2-4\right)=0\)
\(\sqrt{x-2}+\dfrac{1}{3}=1\)
Thực hiện phép tính hợp lý (nếu có thể) :
a) (31dfrac{6}{13} + 5dfrac{9}{41} ) - 36dfrac{6}{13}
b) dfrac{5}{3} +( dfrac{-2}{7} ) - (-1,2)
c) 0,25 + dfrac{3}{5} - (dfrac{1}{8} - dfrac{2}{5} + 1dfrac{1}{4} )
Đọc tiếp
Thực hiện phép tính hợp lý (nếu có thể) :
a) (\(31\dfrac{6}{13}\) + \(5\dfrac{9}{41}\) ) - \(36\dfrac{6}{13}\)
b) \(\dfrac{5}{3}\) +( \(\dfrac{-2}{7}\) ) - (-1,2)
c) 0,25 + \(\dfrac{3}{5}\) - (\(\dfrac{1}{8}\) - \(\dfrac{2}{5}\) + \(1\dfrac{1}{4}\) )
\(-\dfrac{5}{12}+\dfrac{4}{37}+\dfrac{7}{12}-\dfrac{41}{37}+\dfrac{1}{2}\)
\(\dfrac{1}{2}-\dfrac{-2}{5}+\dfrac{1}{3}+\dfrac{5}{7}-\dfrac{-1}{6}+\dfrac{-4}{35}-\dfrac{1}{41}\)
