怎样使5x [] 2x [] x [] 3 [] 4x =6x/3等式成立?
[]中填入分别+,-,*,/,且每个符号只能用一次.
再清楚点啊,看不懂
6x/3=2x???
题目中可以加括号么
如果不可以应该没有答案,一共24种填法我都试了
???
Good Luck!!!
让x=0
-一共就16种情况,自己算算就知道了。
5x + 2x - x * 3 / 4x = ?
5x + 2x - x / 3 * 4x = ?
5x + 2x * x - 3 / 4x = ?
5x + 2x * x / 3 - 4x = ?
5x - 2x + x * 3 / 4x = ?
5x - 2x + x / 3 * 4x = ?
5...
