345 x 25 x 3 x 4
= 345 x 3 x 25 x 4
= 1035 x 100
= 103 500

345 x 69 - 63 x 345 + 345 x 4
= 345 x ( 69 - 63 + 4 )
= 345 x 10
= 3450

a) 1345 x 37 + 43 x 1345 + 1345 x 18 + 2690
= 1345 x 37 + 43 x 1345 + 1345 x 18 + 1345 x 2
=1345 x (37 + 43 + 18 + 2)
=1345 x 100
=134500
b) (237 x 478 + 45678 : 345) x (23 x 25 - 575)
=(237 x 478 + 45678 : 345) x (575 - 575)
=(237 x 478 + 45678 : 345) x 0
=0

345 + 1035 x 5 - 5 x 690 - 345 x 5 + 1000
= 345 + ( 1035 - 690 - 345 ) x 5 + 1000
= 345 + 0 x 5 + 1000
= 345 + 0 + 1000
= 1345 Mong câu trả lời của mk giúp ích cho bn( )
