250x17x4用脱式计算怎么算

0.25x1.38x4 =(0.25x4)x1.38 =1x1.38 =1.38

17.8x(1.78x4)脱式计算简便 17.8×(1.78×4) =17.8×7.12 =126.736.

2.5×0.36×4 =2.5×4×0.36 =10×0.36 =3.6 你好,本题已解答,如果满意 请点右上角“采纳答案”。

(125x25)x4 =125×(25×4) =125×100 =12500

脱式计算 2.4x4.5 =2.4x0.5x9 =1.2x9 =10.8

25×6576×4 =25×4×6576 =100×6576 =657600

1602*16 诸如此类 其实根本不用脱式计算 你只要将前面的因数每个位数与后面的因数相乘就行了 我就这么做的 很爽

96÷[(20-12)x4] =96÷(8×4) =96÷32 =3

60一(66一60)x4 =60-6x4 =60-24 =36 希望能帮到你!

240÷ [ (92一7)÷5] =240÷ [ 85÷5 ] =240÷17 =240/17 26x4一125÷5 =(25+1)×4-25 =100+4-25 =79 330÷ [ 124一(85十17)] =330÷ [ 124-102 ] =330÷22 =330÷11÷2 =30÷2 =15
