    This is the question

    1. State the main property that two compatible observables Aˆ and Bˆ satisfy

      The ^ are above the A and the B.

    Compatible observables mean that the operators corresponding to the observables commute. So [A, B] = 0

    It also means that you can measure their respective observables simultaneously without an uncertainty being present. For example, x-position and x-momentum have incompatible operators, hence the HUP.
