Đáp án + Giải thích các bước giải:
`Câu` `4` :
`a)` `32145` `+` `423507` x `2`
= `32145` `+` `847014`
= `879159`
--------------------------------------------------------------------
`843275` `–` `123568` × `5`
= `5` x (`168655 `-` `123568`)
= `5` x `45087`
= `225435`
--------------------------------------------------------------------
`b)``1207` x `8` `+` `24573`
= `9656` `+` `24573`
= `34229`
--------------------------------------------------------------------
`609` x `9` `-` `4845`
= `5481` `-` `4845`
= `636`
Câu `4`: Tính:
`a)` `32 145 + 423 507 xx 2`
`= 32 145 + 847 014`
`= 879 159`
___________________________
`843 275 - 123 568 xx 5`
`= 843 275 - 617 840`
`= 224 435`
____________________________
`b)` `1207 xx 8 + 24 573`
`= 9656 + 24 573`
`= 34 229`
_____________________________
`609 xx 9 - 4845`
`= 5481 - 4845`
`= 686`
