Answer 1

5.6*128+44*12.8,的简便算法该怎么算列脱式计算
5.6x128+44x12.8
=56x128/10+44x12.8
=(56+44)x12.8
=100x12.8
=1280

Answer 2

5.6×128+44×12.8的简便运算，应该是这样的，（5.6+4.4) ×128=10×128，它的结果就是1280

Answer 3

5.6×128+44×12.8
=5.6×10×12.8+44×12.8
=56×12.8+44×12.8
=（56+44）×12.8
=100×12.8
=1280

Answer 4

原式=56×12.8+44×12.8=12.8×(56+44)=12.8×100=1280

Answer 5

5.6*128+44*12.8
=128*（5.6+4.4）
=128*10
=1280
