Question

0.125x0.25x0.5x256简便运算怎么算？

Answer 1

0.125×0.25×0.5×256
＝0.125×0.25×(0.5×256)
＝0.125×0.25×128
＝0.125×0.25×4×8×4
＝(0.125×8)×(0.25×4)×4
＝1×1×4
＝4

Answer 2

这道题目可以用综合运算的分配律和结合律来简便计算：0.125×0.25×0.5×256=(0.125×8)×(0.25×4)×(0.5×8)=1×1×4=4

Answer 3

多项式简便计算解析：
观察多项式就行化简，0.125＝1/8；0.25＝1/4；0.5＝1/2；256＝2×128＝2×2×64＝2×2×2×32＝2×2×2×2×16＝2×2×2×2×2×8＝4×2×4×8
解：0.125×0.25×0.5×256
＝1/8×1/4×1/2×256
＝1/8×1/4×1/2×8×4×2×4
＝4
即原式＝4。

Answer 4

根据题目要求
0.125×0.25×0.5×256
=0.125×0.25×0.5×8×32
=0.125×8×0.25×4×8×0.5
=4

Answer 5

因为256＝8×4×2×8
根据0.125×8＝0.25×4＝0.5×2＝1
原式＝0.125×8×0.25×4×0.5×2×8
＝8
