这个题目可以采用转换法计算,把45.6x4.6转换为4.56x46,属于等量转换,就可以这样算:4.56x46+4.56x54=4.56x(46+54)=4.56x100=456。

首先运用乘法的性质,把4.56变成45.6,把54变成5.4,然后运用乘法分配等于45.6×(4.6+5.4)=456本回答被网友采纳

简便运算方法如下:
45.6×4.6+4.56×54
=45.6×4.6+45.6×5.4
=45.6×(4.6+5.4)
=45.6×10
=456
45.6×4.6+4.56×54
=45.6×4.6+45.6×5.4
=45.6×(4.6+5.4)
=45.6×10
=456

45.6×4.6+4.56×54
=4.56×10×4.6+4.56×54
=4.56×46+4.56×54
=4.56×(46+54)
=4.56×100
=456
=4.56×10×4.6+4.56×54
=4.56×46+4.56×54
=4.56×(46+54)
=4.56×100
=456

45.6ⅹ4.6+4.56ⅹ54
=4.56ⅹ46+4.56ⅹ54
=4.56ⅹ(46+54)
=456
=4.56ⅹ46+4.56ⅹ54
=4.56ⅹ(46+54)
=456
