4.28*1.9+1.9*5.72简便计算怎么算4.28*1.9+1.9*5.72简便计算怎么算4.28*1.9+1.9*5.72简便计算怎么算4.28*1.9+1.9*5.72=1.9*(4.28+
4.28*1.9+1.9*5.72简便计算怎么算
4.28*1.9+1.9*5.72简便计算怎么算
4.28*1.9+1.9*5.72简便计算怎么算
4.28*1.9+1.9*5.72
=1.9*(4.28+5.72)
=1.9*10
=19
4.28×1.9+1.9×5.72
=1.9(4.28+5.72)
=1.9×10
=19
这个是乘法分配率噢,算法各位大侠都说了,我不再重复。
请采纳呕
