Homework Statement
Show that any linear operator [itex]\hat{L}[/itex] can be written as [itex]\hat{L} = \hat{A} + i\hat{B}[/itex], where [itex]\hat{A}[/itex] and [itex]\hat{B}[/itex] are Hermitian operators.
Homework Equations
The properties of hermitian operators.
The Attempt at a Solution
I am not sure where to start with this one. For example, we know that if an operator, A is hermitian, then [itex]\langle g\mid A f \rangle = \langle f\mid A g\rangle^*[/itex]. But I do not see how to break up L into any combination of other operators. Any help would be appreciated, perhaps a nudge in the right direction.
