请解答？谢谢！

Answer 1

一共有12组解，如下：

6*8/(9-7)=24
(6*8)/(9-7)=24
6*(8/(9-7))=24
6/(9-7)*8=24
(6/(9-7))*8=24
6/((9-7)/8)=24
8*6/(9-7)=24
(8*6)/(9-7)=24
8*(6/(9-7))=24
8/(9-7)*6=24
(8/(9-7))*6=24
8/((9-7)/6)=24

Answer 2

1: 6 × (8 ÷ (9 - 7))
2: 6 × 8 ÷(9 - 7)
3: (6 × 8) ÷ (9 - 7)
4: (6 ÷ (9 - 7)) × 8
5: 6 ÷ (9 - 7) × 8
6: 6 ÷ ((9 - 7) ÷ 8)
7: 8 × (6 ÷ (9 - 7))
8: 8 × 6 ÷(9 - 7)
9: (8 × 6) ÷ (9 - 7)
10: (8 ÷ (9 - 7)) × 6
11: 8 ÷ (9 - 7) × 6
12: 8 ÷ ((9 - 7) ÷ 6)
