(4.6x6.38+3.6x4.6)+9.2 要算式过程..
（4.6×6.38+3.6×4.6）+9.2
=4.6×（6.38+3.6）+9.2
=4.6×9.98+9.2
=4.6×（10-0.02）+9.2
=46-0.092+9.2
=55.108
原式
=4.6x(6.38+3.6)+9.2
=4.6x(6.4+3.6-0.02)+9.2
=4.6x10-4.6x0.02+9.2
=46+9.2-0.092
=55.108
原式=(4.6x6.38+3.6x4.6)+4.6x2=4.6x（6.38+3.6+2）=4.6x11.98=55.108
=29.348+16.56+9.2
=55.108
