215 . 869 + 215 . 14
= 215 . ( 869 + 14 )
= 215 . 883
= 189945
Bài làm:
\(215\times869+215\times14\)
\(=215\times\left(869+14\right)\)
\(=215\times883\)
\(=189845\)
215 x 869 + 215 x 14
=215(869 + 14)
=215 x 883
=189845
215 x 869 +215 x 14
=215 x (869 + 14)
=215 x 883
=189845
215×869+215×14
215×(869+14)
215×883
189845
Trl:
