134 x 100 + 250 x 100 - 84 x 100
= (134 + 250 - 84) x 100
= 300 x 100
= 30 000
=13400 + 25000 - 8400 = 30 000
dễ ợt !!!
bạn nào thấy vậy thì tk nhé
134*100 + 250*100 - 84*100 = (134 + 250 - 84)*100 = 300*100 = 30000
134 x 100 + 250 x 100 - 84 = 100 x ( 134 + 250 - 84 )
= 100 x 300
= 30000
134 x 100 + 250 x 100 - 84 x 100
= (134 + 250 - 84) x 100
= 300 x 100
= 30000
134 x 100 + 250 x 100 - 84 x 100

= 100 x 300
= 30000
134 x 100 + 250x100-84x100
=(134+250 - 84) x 100
= 300 x 100
= 30000
134x100+250x100-84x100
= 100x(134+250-84)
= 100x300
= 30 000
134*100+250*100-84*100
