We take the complex conjugate and multiply it by the complex number as done in (1). Hence, we define the product zz¯ as the square of the Absolute value or modulus of a complex number. Therefore, we can write zz¯ = |z| 2. This is done because as we just discussed, zz¯ gives a way to measure the Absolute value or magnitude of our complex number.I just started my topic on complex numbers and I'm stuck on this question. What I have managed to get (I go wrong here, I don't know where though): z2 = (a + bi)2 =a2 +b2 z 2 = ( a + b i) 2 = a 2 + b 2, so |z2| = (a2 +b2)2 +02− −−−−−−−−−−−√ = a4 + 2a2b2 +b4− −−−−−−−−−−−√ | z 2 | = ( a 2 + b 2 ...

Answer: A complex number is defined as the addition of a real number and an imaginary number. It is represented as “z” and is in the form of (a + ib), where a and b are real numbers and i is an imaginary unit whose value is √ (-1). The real part of the complex number is represented as Re (z), and its imaginary part is represented as Im (z).Unit Imaginary Number. The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √ (−1) is i for imaginary. But in electronics the symbol is j, because i is used for current, and j is next in the alphabet.Standard normal table.
