The discussion revolves around solving the equation 1/z = -4 + 4i, specifically focusing on the representation of complex numbers in the form a + bi. Participants are examining the correctness of a solution and the format in which the answer should be presented.
Participants are actively discussing the representation of the answer, with some asserting that the original poster's result is correct. There is a suggestion to present the answer in a different numerical format, indicating a productive direction in the conversation.
There is mention of an online quiz that may have discrepancies, leading to confusion regarding the correctness of the solution. The requirement to express complex numbers in a specific format is also under discussion.
Your result is right, but you might write it in the form ##-\frac{1}{8}- \frac{1}{8} i##53Mark53 said:Homework Statement
How would I go about solving 1/z=(-4+4i)
The answer that I keep on getting is wrong
The Attempt at a Solution
[/B]
What I did
z=1/(-4+4i)x(-4-4i)/(-4-4i)
z=(-4-4i)/(16+16i-16i-16i^2)
z=(-4-4i)/32
z=-1/8-i/8
This is the answer that I got however it says that it is wrong. I am unsure what else I can do
Thanks for any help
Thanks! I thought I was right, the online quiz that we have must have a mistake thenehild said:Your result is right, but you might write it in the form ##-\frac{1}{8}- \frac{1}{8} i##
No, it was there. This is what the OP wrote:chwala said:Complex numbers ##z##, have to be expressed in the form ##z= a+bi##, where ##a, b##, are real numbers, this was missing in your solution, the ##"i"##
z=-1/8-i/8
Maybe you should write 0.125 instead of 1/8.53Mark53 said:Thanks! I thought I was right, the online quiz that we have must have a mistake then
