hok tốt .
63*66+63*54+120*37
=63*(66+54)+120*37

63 x 66 + 63 x 54 + 120 x 37
= 63 x (66 +54) + 120 x 37
= 63 x 120 + 120 x 37
= 120 x (63 +37)
= 120 x 100
= 12000
Chúc bạn học tốt
\(63\times66+63\times54+120\times37\)
\(=63\times\left(66+54\right)+120\times37\)
\(=63\times120+120\times37\)
\(=\left(63+37\right)\times120\)
\(=100\times120\)
\(=12000\)
63 x 66 + 63 x 54 + 120 x 37
= 63 x (66 + 54) + 120 x 37
= 63 x 120 + 120 x 37
= 120 x (63 + 37)
= 120 x 100
= 12000
