Plz solve Question 7

v (x) is an eigenfunction of corresponding to eigenvalue 4. If the commutator bracket of two operators and is equal to zero i.e. [A, B]=0, then the physical observables corresponding to these operators are simultaneously accurately measurable and they have a com- plete set of simultaneous eigenfunctions. d Example 7: The operator x+ has the eigenvalue a. Determine the corresponding wavefunction. dx
