Concept:-

For linear and position momentum:

[x̂, p̂x] = iℏ   ....(1)

[p̂x, x̂] = -iℏ   ...(2)

[x̂n, p̂x] = nxn-1 [x, p̂x]   ....(3)

[p̂xn, x̂] = npxn-1[p̂x, x̂] .....(4)

Explanation:-

  • Given that the commutator 

...........(5)

  • Now using equation (4) and (1),

[p̂x, x̂] = -iℏ 

  • Now, from equation (5) we get,

=

Conclusion:-

Hence, the value of  is
