4.5x12.6-3.6x4.5+4.5简便计算还有45.6x6.7+4.56x31+0.456x20今天答完
4.5×12.6－3.6×4.5＋4.5
＝4.5×（12.6－3.6＋1）
＝4.5×10
＝45
45.6×6.7＋4.56×31＋0.456×20
＝4.56×67＋4.56×31＋4.56×2
＝4.56×（67＋31＋2）
＝4.56×100
＝456

4.5x12.6-3.6x4.5+4.5
=4.5x(12.6-3.6+1)
=4.5x10
=45
45.6x6.7+4.56x31+0.456x20
=4.56x67+4.56x31+4.56x2
=4.56x(67+31+2)
=4.56x100
=456

4.5x12.6-3.6x4.5+4.5
=4.5x(12.6-3.6+1)
=4.5x10
=45
45.6x6.7+4.56x31+0.456x20
=4.56x(67+31+2)
=4.56x100
=456

=4.5x(12.6-3.6+1)
=4.5x10
=45


=4.56x67+4.56x31+4.56x2
=4.56x(67+31+2)
=4.56x100
=456
希望能帮你忙，不懂请追问，懂了请采纳，谢谢
