WebSimply multiplying the two phasors of voltage and current, without first taking the complex conjugate of current, gives this: V0 ⋅ ejϕV ⋅ I0 ⋅ ejϕI = V0 ⋅ I0 ⋅ ej(ϕV + ϕI) If you look closely there, you will see ϕV + ϕI and not the desired ϕV − ϕI. So the answer is just wrong and is therefore useless.
