12,3 x 3,12 + 12,3 + 6,48
= 12,3 x ( 3,12 + 6,48 )
= 12,3 x 10
= 123
2,23 x 8,56 + 8,56 x 7,77
= 8,56 x ( 2,23 + 7,77 )
= 8,56 x 10
= 85,6
4,98 x 67,34 + 32,66 + 4,98
= 4,98 x ( 67,34 + 32,66 )
= 4,98 x 100
= 498
Nhớ tick mik nha !!!
12,3x3,12+12,3x6,48
=12,3x(3,12+6,48)
=12,3x9,6
=118,08
2,23x8,56+8,56x7,77
=8,56x(2,23+7,77)
=8,56x10
=85,6
4,98x67,34+32,66x4,98
=4,98x(67,34+32,66)

nếu đúng thì tick cho tớ nhé
12,3 x 3,12 + 12,3 x 6,48
= 12,3 x 3,12 + 12,3 x (3,12 + 3,12)
