Identify real and imaginary parts: Identify the real part (Re(z)) and the imaginary part (Im(z)) of the complex number z=6−3i.The real part is the coefficient of the real unit (1), and the imaginary part is the coefficient of the imaginary unit (i).
Real part of z: The real part of z is the number before the subtraction sign, which is 6.Re(z)=6
Imaginary part of z: The imaginary part of z is the number before the imaginary unit i, which is −3.Im(z)=−3
