Use the eight numbers 2, 4, 6, 8, 10, 12, 14 and 16 to fill in the following formula. Each number can only be filled in once, so the minimum value of the calculation result is______ , the maximum value is______ ．□×□+□×□×□+□×□×□

Use the eight numbers 2, 4, 6, 8, 10, 12, 14 and 16 to fill in the following formula. Each number can only be filled in once, so the minimum value of the calculation result is______ , the maximum value is______ ．□×□+□×□×□+□×□×□

The minimum value of calculation result: 16 × 14 + 2 × 8 × 12 + 4 × 6 × 10 = 656; the maximum value of calculation result: 2 × 4 + 6 × 8 × 10 + 12 × 14 × 16 = 3176; so the answer is: 6563176

How to calculate 14 / 5 - (2.8-5 / 7) + 2 / 7
Same as 3 / 7 - [19 / 5 - (14 / 5 + 4 / 7)]
3/5÷[(1/5+1/3)÷2/9]

14/5-（2.8-5/7)+2/7
＝（2.8-2.8）+（5/7+2/7）
＝0+1
＝1
3/7-[19/5-(14/5+4/7)]
＝3/7－（19/5－14/5－4/7）
＝（3/7+4/7）－（19/5-14/5）
＝1－1
＝0
3/5÷[(1/5+1/3)÷2/9]
＝3/5÷[8/15÷2/9]
