拜托,中间没有÷(1-1/4)
追答应该是题目漏印了!
如果没有÷(1-1/4)
则
1÷(1-1/2)÷(1-1/4)÷(1-1/5)······÷(1-1/2006),
=[1÷(1/2)÷(2/3)÷(3/4)÷(4/5)······÷(2005/2006)] x(3/4)
=[1x2x(3/2)x(4/3)x(5/4)x.........x(2006/2005)] x(3/4)
=2006 x(3/4)
=1504.5
是没有÷(1-1/4),不是没有÷(1-1/3)
追答对不起,打错了,不影响得数!
1÷(1-1/2)÷(1-1/3)÷(1-1/5)······÷(1-1/2006),
=[1÷(1/2)÷(2/3)÷(3/4)÷(4/5)······÷(2005/2006)] x(3/4)
=[1x2x(3/2)x(4/3)x(5/4)x.........x(2006/2005)] x(3/4)
=2006 x(3/4)
=1504.5
假如不是印漏的问题呢
追答这里就是按照不是印漏的情况来解题的啊!

这类题目,首先的思路就是要去掉绝对值符号。我们看每一项:例如|1\/3-1\/2|中,1\/3-1\/2是小于0的,去掉绝对值符号,应该要变成:-(1\/3-1\/2);包括后面的各项也是:|1\/4-1\/3|中,1\/4-1\/3也是小于0的,去掉绝对值符号时要加个负号,应该变成:-(1\/4-1\/3),那么就可以找到规律啦~...
