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

6, 9, 7, 5的24点答案: 1: 6 + (9 × (7 - 5)) 2: 6 + 9 ×(7 - 5) 3: 6 - (9 × (5 - 7)) 4: 6 - 9 ×(5 - 7) 5: 6 + (7 - 5) × 9 6: 6 + ((7 - 5) × 9) 7: 6 - (5 - 7) × 9 8: 6 - ((5 - 7) × 9) 9: (9 × (7 - 5)) + 6 10: 9 × (7 - 5) + 6 11: (...

1. ﹙9+7﹚× 6 ÷ 4 2. ﹙9+7﹚÷ 4 × 6 3. ﹙7+9﹚÷﹙4 ÷ 6﹚

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

{6+6}x{9-7}=24

(5-7÷7)×6=24 如有疑问,请追问;如已解决,请采纳

((6’)!+(7‘)!+(9’)!+(10‘)!)!=24 求24点的万能公式,这边用到了求导和阶乘,我们知道常数的求导全是0,而0!=1

有以下几种方法可以得到24: 6x(7+9-12)=6x4=24[7+﹙9-12﹚]×6=24[9+﹙7-12﹚]×6=24[6×﹙9-7﹚]+12=24 拓展资料: 解题技巧: 一般说来,运算都指代数运算,它是集合中的一种对应。 对于集合A中的一对按次序取出的元素a、b,有集合A中唯一...

只用加减乘除无解,用根号或阶乘则可,如: [13×(7-6)-9]!=4!=24 根号9×(13-7)+6=24

[6-(7+11)÷9]!=4!=4×3×2×1=24
