Có nhiều cách để giải, sau đay là một cách tính:
\(\left(572\cdot7+266\right)\cdot\left(366\cdot9-168\cdot18\right)\cdot\left(348\cdot6-348\right)\)
\(=\left(286\cdot7\cdot2+133\cdot2\right)\cdot\left(366\cdot9-168\cdot2\cdot9\right)\cdot\left(348\cdot6-348\right)\)
\(=\left(2002\cdot2+133\cdot2\right)\cdot\left(366\cdot9-336\cdot9\right)\cdot\left(348\cdot6-348\right)\)
\(=\left[2\cdot\left(2002+133\right)\right]\cdot\left[9\cdot\left(366-336\right)\right]\cdot\left[348\cdot\left(6-1\right)\right]\)
\(=2\cdot2135\cdot9\cdot30\cdot348\cdot5\)
\(=\left(2\cdot5\right)\cdot30\cdot2135\cdot348\cdot9\)
\(=10\cdot30\cdot2135\cdot348\cdot9\)
\(=\left(10\cdot30\cdot9\right)\cdot\left(2135\cdot348\right)\)
\(=\left(300\cdot9\right)\cdot\left(2135\cdot348\right)\)
\(=2700\cdot742980\)
\(=\left(27\cdot100\right)\cdot\left(74298\cdot10\right)\)
\(=\left(27\cdot74298\right)\cdot\left(100\cdot10\right)\)
\(=2006046\cdot1000\)
\(=2006046000\)
