12 x 2 + 12 x 8
= 12 x ( 2 + 8 )
= 12 x 10
= 120

\(12\cdot2+12\cdot8\)
\(=12\cdot\left(2+8\right)\)
\(=12\cdot10\)
\(=120\)
\(12\times2+12\times8\)
\(=12\times\left(2+8\right)\)
\(=12\times10\)
\(=120\)
mk nhất đó
\(12.2+12.8=12.\left(8+2\right)=12.10=120\)
12 . 8 + 12 . 2
= 12 . (8 + 2)
= 12 . 10
= 120.
