怎样使1/2( )1/3( )1/4( )1/5（ )1/6括号里添加减乘除使这个式子最大?必须都填不一样的

都填除号是不是就可以了，这样就相当于是1/2*3*4*5*6了

(1/2) + (1/3) / (1/4) - (1/5) * (1/6) = 1.800000000 (1/2) + (1/3) * (1/4) - (1/5) / (1/6) = -0.6166666667 (1/2) * (1/3) + (1/4) - (1/5) / (1/6) = -0.7833333333 (1/2) - (1/3) / (1/4) + (1/5) * (1/6) = -0.7999999997 (1/2) * (1/3) - (1/4) / (1/5) + (1/6) = -0.9166666663 (1/2) - (1/3) * (1/4) / (1/5) + (1/6) = 0.2500000000 (1/2) / (1/3) * (1/4) - (1/5) + (1/6) = 0.3416666667 (1/2) - (1/3) + (1/4) / (1/5) * (1/6) = 0.3750000000 (1/2) - (1/3) / (1/4) * (1/5) + (1/6) = 0.4000000000 (1/2) / (1/3) * (1/4) + (1/5) - (1/6) = 0.4083333333 (1/2) - (1/3) + (1/4) * (1/5) / (1/6) = 0.4666666667 (1/2) + (1/3) - (1/4) * (1/5) / (1/6) = 0.5333333333 (1/2) + (1/3) / (1/4) * (1/5) - (1/6) = 0.6000000000 (1/2) + (1/3) - (1/4) / (1/5) * (1/6) = 0.6250000000 (1/2) * (1/3) / (1/4) - (1/5) + (1/6) = 0.6333333335 (1/2) * (1/3) / (1/4) + (1/5) - (1/6) = 0.7000000001 (1/2) + (1/3) * (1/4) / (1/5) - (1/6) = 0.7500000000 (1/2) * (1/3) - (1/4) + (1/5) / (1/6) = 1.116666667 (1/2) * (1/3) + (1/4) / (1/5) - (1/6) = 1.250000000 (1/2) / (1/3) - (1/4) + (1/5) * (1/6) = 1.283333333 (1/2) / (1/3) + (1/4) * (1/5) - (1/6) = 1.383333333 (1/2) / (1/3) - (1/4) * (1/5) + (1/6) = 1.616666667 (1/2) - (1/3) * (1/4) + (1/5) / (1/6) = 1.616666667 (1/2) / (1/3) + (1/4) - (1/5) * (1/6) = 1.716666667 (1/2) + (1/3) / (1/4) - (1/5) * (1/6) = 1.800000000赞同 0| 评论

必须是都填不一样的

答案： (1/2) + (1/3) / (1/4) - (1/5) * (1/6) = 1.800000000 所有结果： (1/2) + (1/3) * (1/4) - (1/5) / (1/6) = -0.6166666667 (1/2) * (1/3) + (1/4) - (1/5) / (1/6) = -0.7833333333 (1/2) - (1/3) / (1/4) + (1/5) * (1/6) = -0.7999999997 (1/2) * (1/3) - (1/4) / (1/5) + (1/6) = -0.9166666663 (1/2) - (1/3) * (1/4) / (1/5) + (1/6) = 0.2500000000 (1/2) / (1/3) * (1/4) - (1/5) + (1/6) = 0.3416666667 (1/2) - (1/3) + (1/4) / (1/5) * (1/6) = 0.3750000000 (1/2) - (1/3) / (1/4) * (1/5) + (1/6) = 0.4000000000 (1/2) / (1/3) * (1/4) + (1/5) - (1/6) = 0.4083333333 (1/2) - (1/3) + (1/4) * (1/5) / (1/6) = 0.4666666667 (1/2) + (1/3) - (1/4) * (1/5) / (1/6) = 0.5333333333 (1/2) + (1/3) / (1/4) * (1/5) - (1/6) = 0.6000000000 (1/2) + (1/3) - (1/4) / (1/5) * (1/6) = 0.6250000000 (1/2) * (1/3) / (1/4) - (1/5) + (1/6) = 0.6333333335 (1/2) * (1/3) / (1/4) + (1/5) - (1/6) = 0.7000000001 (1/2) + (1/3) * (1/4) / (1/5) - (1/6) = 0.7500000000 (1/2) * (1/3) - (1/4) + (1/5) / (1/6) = 1.116666667 (1/2) * (1/3) + (1/4) / (1/5) - (1/6) = 1.250000000 (1/2) / (1/3) - (1/4) + (1/5) * (1/6) = 1.283333333 (1/2) / (1/3) + (1/4) * (1/5) - (1/6) = 1.383333333 (1/2) / (1/3) - (1/4) * (1/5) + (1/6) = 1.616666667 (1/2) - (1/3) * (1/4) + (1/5) / (1/6) = 1.616666667 (1/2) / (1/3) + (1/4) - (1/5) * (1/6) = 1.716666667 (1/2) + (1/3) / (1/4) - (1/5) * (1/6) = 1.800000000

答案：(1/2) + (1/3) / (1/4) - (1/5) * (1/6) = 1.800000000 所有结果：(1/2) + (1/3) * (1/4) - (1/5) / (1/6) = -0.6166666667 (1/2) * (1/3) + (1/4) - (1/5) / (1/6) = -0.7833333333 (1/2) - (1/3) / (1/4) + ...
