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.

TopNewestThat.s not what happened. I was on a PARTICULAR problem on the web site. I entered my answer in the space provided for THAT problem. When I hit enter, I was taken to the answer for ANOTHER problem, and was told my answer was wrong. – Verlen Coy · 1 year, 11 months ago

Please help me trace out what happened. This is my interpretation of your described list of events

I believe you are referring to the Facebook post, which asks you to calculate \( \left( \frac{ 1-i} { 1+i} \right) ^ { 112 } \).

Clicking on that Facebook post you landed in the practice section of "Complex Numbers Problem Solving - Basic". We asked you to calculate \( \left( \frac{ 1-i} { 1+i} \right) ^ { 148 } \). We are aware that in the practice section, you could be shown a slightly different problem.

Thanks for reporting this issue. This is the first time I have heard of it, and I will need to look into what's happening.

Can you provide more details about what happened?

Do you recall which problem you were shown? Can you confirm if it is a problem regarding \( \frac{ 7 - \sqrt{ -16} } { 7 + \sqrt{- 16 } } \)?

Did this happen on another problem where you did not come from facebook into the practice section? – Calvin Lin Staff · 1 year, 11 months ago

The problem was (1-i)/(1+i) to the 148th; the answer it jumped to was for (7-SR-16)/(7+SR-16).Log in to reply

Hi Verlen, For links back into the quizzes, we store your progress that you made and show you the set that you were working on. As a result, you might end up seeing a different problem, though it is still in the same skill.

If you incorrectly answered the last problem, then it will display that you are incorrect. – Calvin Lin Staff · 1 year, 11 months ago
