Question

\(\left(\dfrac{-2}{3}\right)^2\)+\(\dfrac{1}{6}\)\(-\left(0.5\right)^3\)

 

 

 

 

Answer 1

\(\left(\dfrac{-2}{3}\right)^2+\dfrac{1}{6}-\left(0,5\right)^3\)

\(=\dfrac{4}{9}+\dfrac{1}{6}-\dfrac{1}{8}\)

\(=\dfrac{24}{54}+\dfrac{9}{54}-\dfrac{1}{8}\)

\(=\dfrac{11}{18}-\dfrac{1}{8}\)

\(=\dfrac{88}{144}-\dfrac{18}{144}\)

\(=\dfrac{35}{72}\)

Answer 2

\(\left(\dfrac{-2}{3}\right)^2+\dfrac{1}{6}-\left(0,5\right)^3\)
\(=\dfrac{4}{9}+\dfrac{1}{6}-\dfrac{1}{8}\)

\(=\dfrac{32}{72}+\dfrac{12}{72}-\dfrac{9}{72}\)

\(=\dfrac{35}{72}\)

Answer 3

\(\left(-\dfrac{2}{3}\right)^2+\dfrac{1}{6}-\left(-0,5\right)^3\)

\(\left(-\dfrac{2}{3}\right)^2+\dfrac{1}{6}+\left(0,5\right)^3\)

\(\dfrac{4}{9}+\dfrac{1}{6}+\dfrac{1}{8}\)

\(=\dfrac{11}{18}+\dfrac{1}{8}=\dfrac{53}{72}\)
