On 1-24-15 at 11 PM you posted a problem asking for value of [(1-i)/(1+i)] to the 112th power. Following the link to the web site, I found the power in the problem changed to 148th. When I entered my answer, the web site jumped me to a completely different problem and indicated my answer was wrong. This is not the first problem this has happened with. Please make sure your links are correct.
