hok tốt nhé!
64 x 56 + 81 x 44 + 17 x 56
= 56 x ( 64 + 17 ) + 81 x 44
= 56 x 81 + 81 x 44
= 81 x ( 56 + 44 )
= 81 x 100
= 8100
= 56 x (64+17) + 81 x 44
= 56 x 81 + 81 x 44
= 81 x (56+44)
= 81 x 100
= 8100
64 x 56 + 81 x 44 + 17 x 56
= 56 x ( 17 + 64 ) + 81 x 44
= 56 x 81 + 81 x 44
= 81 x ( 56 + 44 )
= 81 x 100
= 8100
\(64\times56+81\times44+17\times56\)
\(=\left(64+17\right)\times56+81\times44\)
