Question

the Re (z) in 3+7i is​

Answer 1

Answer:

Step-by-step explanation:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i ). This means that it either goes from positive to negative or from negative to positive. As a general rule, the complex conjugate of a+bi is a−bi . Therefore, the complex conjugate of 3−7i is 3+7i
