What is z bar in complex numbers?

Answer: A real number and an imaginary number are combined to form a complex number.

Z=a+ib, where a,b ∈ R and i is an imaginary number, is used to denote a complex number.

Z is the conjugate of Z in the complex number system.

A complex number’s conjugate is another complex number with the same real portion as the original and an imaginary part that has the same magnitude but a different sign.

If Z=a+ib is a complex number, then Z=a-ib is its conjugate.
