\(4.9.28+12.3.82+64.69+4.16.41=36.28+36.82+64.69+64.41=36\left(28+82\right)+64\left(69+41\right)=36.110+64.110=110\left(36+64\right)=110.100=11000\)
\(4\cdot9\cdot28+12\cdot3\cdot82+64\cdot69+4\cdot16\cdot41\)
\(=4\cdot\left(9\cdot28+16\cdot41\right)+3\cdot\left(12\cdot82+64\cdot23\right)\)
\(=4\cdot908+3\cdot2456=11000\)
