What are 3+4i and 3−4i to each other?
回答 (6)
one is the complex conjugate of the other
Both are complex conjugates of each other
Complex conjugates
a±bi and a∓bi are complex conjugates.
The sum of complex conjugates is Real. e.g. (3+4i)+(3-4i) = 6+0i
The product of complex conjugates is Real. e.g. (3+4i)(3-4i) = 25+0i
The conjugate of 3 + 4i is 3 - 4i.
