142,742 nếu đúng thì k cho mình nha !!!
65.142+100.15-42.65+20.100
= 65 . (142 - 42) + 100 . (15 + 20)
= 65 . 100 + 100 . 35
= 100 . (65 + 35)
= 100 . 100
= 10000

65.142+100.15-42.65+20.100= 65.142 - 42.65 +100.15 +20.100
= 65(142-42) + 100.(15+20)
= 65.100+100.35
= 100(65+35)
= 100. 100
= 10000
65.142+100.15-42.65+20.100
=65.(142-42)+100.(15+20)

Học giỏi :)))
65.142+100.15-42.65+20.100
= 65(142-42)+100(15+20)
= 65.100+100.35
= (65+35)100
=100.100
= 10000
65 . ( 142 - 42 ) + 100 . ( 15 + 20 )
= 65 . 100 + 100 . 35
= 6500 + 3500
= 10000
