Question

4.3×72+29x4.3-4.3的步骤算法？

Answer 1

4.3×72+29x4.3-4.3的步骤算法如下：
4.3×72+29x4.3-4.3=
提取公因式4.3
4.3X（72+29-1）=
4.3X100=430

Answer 2

（72+29-1）×4.3

＝4.3×100

＝430

Answer 3

4.3×72+29x4.3-4.3的步骤算法：
4.3×72+29x4.3-4.3
=4.3×(72+29-1)
=4.3×100
=430

Answer 4

简便计算方法是:
4.3×72+29x4.3-4.3
＝4.3×72+29×4.3-1×4.3
＝4.3×（72+29-1）
＝4.3×100
＝430

Answer 5

4.3x72+29x4.3-4.3
=4.3x72+29x4.3-4.3x1…把4.3看做4.3x1
=4.3x（72+29-1）…运用乘法分配律
=4.3x100
=430
