\(3,56-\left|\left(\frac{3}{2}\right)^2:\left(\frac{-3}{6}\right)\right|\)
\(=3,56-\left|\frac{3^2}{2^2}:\left(\frac{-3}{6}\right)\right|\)
\(=3,56-\left|\frac{9}{4}.\frac{-6}{3}\right|\)
\(=3,56-\left|\frac{3}{2}.\left(-3\right)\right|\)
\(=3,56-\left|\frac{-1}{2}\right|\)
\(=3,56-\frac{1}{2}\)
\(=3,56-0,5\)
\(=3,06\)
