Question

define a complex number and conjugate of complex number​

Answer 1

Step-by-step explanation:

In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, the complex conjugate of {\displaystyle a+bi} is equal to {\displaystyle a-bi.}

Answer 2

Answer:

Mark me as brainliest and thank me if the answer is useful.

Step-by-step explanation:

Conjugate of a complex number z, is another complex number represented by z¯. It is obtained by changing the sign of i.

So, for z=a+ib then z¯=a−ib

For example, if z=2−7√ i, then z¯=2+7√ i
