\(32\times27+47\times73+27\times15\)
\(=\left(32\times27+27\times15\right)+47\times73\)
\(=27\times\left(32+15\right)+47\times73\)
\(=27\times47+47\times73\)
\(=47\times\left(27+73\right)\)
\(=47\times100\)
\(=4700\)

\(=32\cdot27+27\cdot15+47\cdot73\)
\(=27\cdot\left(32+15\right)+47\cdot73\)
\(=27\cdot47+47\cdot73\)
\(=47\cdot\left(27+73\right)\)
\(=47\cdot100\)
\(=4700\)
32x27+47x73+27x15
=27x (32+15)+47x73
=27x47+47x73
=47x(27+73)
=47x100=4700

\(=4700\)
32x27+47x73+27x15
=27x[32+15]+47x73
=27x47+47x73
=47x[27+73]
=47x100
=4700
học tốt!
32.27+47.73+27.15
=27.(32+15)+47.73
=27.47+47.73
=47.(27+73)
=47.100
=4700
