Question

\(\left\{3\dfrac{17}{18}x[\dfrac{5}{2}-\left(\dfrac{1}{3}+\dfrac{2}{9}\right)\right\}\) : \([\left(-\dfrac{1}{2}\right)+0,25]^2\)

 

Answer 1

\(\left\{3\dfrac{17}{18}\cdot\left[\dfrac{5}{2}-\left(\dfrac{1}{3}+\dfrac{2}{9}\right)\right]\right\}:\left[\left(-\dfrac{1}{2}+0,25\right)\right]^2\)

\(=\left\{\dfrac{71}{18}\cdot\left[\dfrac{5}{2}-\dfrac{5}{9}\right]\right\}:\left[\left(-\dfrac{1}{2}+\dfrac{1}{4}\right)\right]^2\)

\(=\dfrac{71}{18}\cdot\dfrac{35}{18}:\left(-\dfrac{1}{4}\right)^2\)

\(=\dfrac{71\cdot35}{324}\cdot16=\dfrac{9940}{81}\)

Answer 2

\(3\dfrac{17}{18}\) x nha
