This time, the real part can be written as Re(A * B) = x * m y * n, and the imaginary part as Im(A * B) = x * n + y * m. Remember that complex number calculators use a negative sign in the real part because, at some point, we are faced with the product of two numbers i * i, which by definition is -1. Most loads in AC systems will have some resistive and some reactive component, so one number is not enough to describe power in these cases. You also have the option to opt-out of these cookies. Multiplication: (3+2i)*(5-3i). Then, the absolute value is: FG=z1cexp(1d)|F^G| = |z_1|^c \cdot \exp(-\varphi_1\!\cdot\!d)FG=z1cexp(1d), while the argument is: arg(FG)=1c+dlnz1\arg(F^G) = \varphi_1c + d\ln|z_1|arg(FG)=1c+dlnz1.
