k mình nha
1,53x72+15,3x5,2+1,53x22-1,53x46
= 1,53x72+1,53x10x5,2+1,53x22-1,53x46
= 1,53x72+1,53x52+1,53x22-1,53x46
= 1,53 × ( 72 + 52 + 22 - 46 )
= 1,53 × 100
= 153
Nếu mình đúng thì các bạn k mình nhé
= 153 nha bạn... Đúng 100 %
Cách làm :
= 1,53 . ( 72 + 22 - 46 ) + 15,3 . 5,2
= 1,53 . 48 + 15,3 . 5,2
= 73,44 + 79,56
= 153
K mình nha
1,53 × 72 + 15,3 × 5,2 + 1,53 × 22 - 1,53 × 46
= 1,53 × 72 + ( 15,3 ÷ 10 ) × ( 5,2 × 10 ) + 1,53 × 22 - 1,53 × 46
= 1,53 × 72 + 1,53 × 52 + 1,53 × 22 - 1,53 × 46
= 1,53 × ( 72 + 52 + 22 - 46 )
= 1,53 × 100
= 153
1,53x72+15,3x5,2+1,53x22-1,53x46
=1,53x72+1,53x52+1,53x22-1,53x46
=1,53x(72+22+52-46)
=1,53x100
=153
