Identify the standard form of a complex number, which is a + bi, where 'a' is the real part and 'b' is the imaginary part.
Examine the given complex number: 3 + 2i√3.
Determine the real part 'a' of the complex number, which is the coefficient of the real number without the imaginary unit 'i'. In this case, 'a' is 3.
Determine the imaginary part 'b' of the complex number, which is the coefficient of the imaginary unit 'i'. In this case, 'b' is 2√3.
Conclude that the real part is 3 and the imaginary part is 2√3, matching the format a = 3, b = 2√3.
