SUMMARY
The expectation value of a general operator A, represented as , allows the complex constant c to be taken outside the bracket without complex conjugation. This is due to the linear nature of quantum mechanics operations, where constants can be factored out of linear operators. In scenarios involving anti-linear operators, such as time-reversal, complex conjugation is necessary; however, this does not apply in the current context of expectation values.
