1 2 4 8 算24点

(1×(2×(4+8))) ((1×2)×(8+4)) (1×((4+8)×2)) ((1×(8-2))×4) (2÷(1÷(4+8))) (2×((4×1)+8)) (2×((8+4)÷1)) ((2×(8+4))×1) ((2×(8+4))÷1) ((4+(1-2))×8) (((4+1)-2)×8) (4×(1×(8-2))) (4×((1×8)-2)) (4÷(1÷(8-2))) ((4×1)×(8-2)) ((4÷1)×(8-2)) ((4...

算法有很多种:

根据题干分析可得:4×8+2-10,=32+2-10,=24,10×2+8-4,=20+8-4,=24.故答案为:4×8+2-10;10×2+8-4.

四则运算范围内有3种算法—— (5-2)×1×8 = 3×8 = 24 (5-1)×(8-2) = 4×6 = 24 (8/2)×(5+1) = 4×6 = 24 加上乘方开根又有3种算法—— (2^5-8)×1 = 32-8 = 24 (5^2)-(1^8) = 25-1 = 24 [√(8×2)]×(5+1) = 4×6 = 24 添上阶乘对数再有2种算法—— [log2(8)]!...

(8÷2)×(1+5)=24

你好,你的这4个数字是不能列式计算得24的,所以此题无解,请采纳!

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...

解:∵已知4、 8、 6、8需运用加、减、乘、除使等式成立 最终结果等于24 根号4 = 正2或负2 舍去=-2 ∴根号4 = 2 ∴6 × 4 × (8 ÷ 8)= 24 × 1 = 24 8 × [6 ÷(8 ÷ 4)] = 8 × (6 ÷ 2)= 8 × 3 = 24 8 + 8 + 6 + 根号4 = 16 + 6 + 2 = 22 + 2 = 24 ...

这可太多了, 有1000多种
