Can I ask a basic question. This was a question in a test, I could not solve this.(adsbygoogle = window.adsbygoogle || []).push({});

When is it true that the result of a single measurement for a dynamical variable is equal to the expectation value of the operator corresponding to that dynamical variable?

Thank you for your help.

Sincerely yours.

Khai.
