用2,4,5,8算24点

共6种不同算法,举例如下: 2×(4×5-8)=24 4×2×(8-5)=24

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

8*(4*2-5) =8*(8-5) =8*3 =24; (8-5)*4*2 =3*4*2 =12*2 =24; 4*5+8/2 =20+4 =24; 8*(5-4+2) =8*3 =24; 8*5/2+4 =40/2+4 =20+4 =24; ……

1. [﹙5+9﹚×2]-4 2. ﹙4+2﹚×﹙9-5﹚ 3. [9-﹙5-2﹚]×4

1.3+5=8,8-2=6,4×6=24 2.3+4+5=12,12×2=24

(5+7)*(4—2)

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)]!...

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

4*5+8/2=24,求采纳

8*(2+5-4)=8*3=24; (8-5)*2*4=3*2*4=24; 2*(4*5-8)=2*12=24; (2*4-5)*8=(8-5)*8=3*8=24; 8/2+5*4=4+20=24;
