Question

[-3/2]^3+-49/24.3/14-[5/8-27/8]

 

Answer 1

Ta có: \(\left(-\dfrac{3}{2}\right)^3+\dfrac{-49}{24}\cdot\dfrac{3}{14}-\left(\dfrac{5}{8}-\dfrac{27}{8}\right)\)

\(=\dfrac{-27}{8}+\dfrac{-7}{2}\cdot\dfrac{1}{8}-\dfrac{-22}{8}\)

\(=\dfrac{-27+22}{8}+\dfrac{-7}{16}\)

\(=\dfrac{-5}{8}+\dfrac{-7}{16}\)

\(=\dfrac{-10}{16}+\dfrac{-7}{16}\)

\(=\dfrac{-17}{16}\)
