發問:
問 要有式 (-3)-(-2)(+3)-(-3)(-4)(-5)= 更新: 仲有 [(+3)-(-4)(-5)]除[(-4)(-3)]
最佳解答:
(-3)-(-2)(+3)-(-3)(-4)(-5) =(-3)-(-2x3)-(-3x4x5) =(-3)-(-6)-(-60) =-3+6+60 = 63==
其他解答:
(-3)-(-2)(+3)-(-3)(-4)(-5) =(-3)-(-6)-(-60) =63 [(+3)-(-4)(-5)] ------------------ [(-4)(-3)] =(+3)-(+20) =(+3)-20 =(-17)|||||(-3)-(-2)(+3)-(-3)(-4)(-5) =(-3)-(-6)-(-60) =63~~~
