Can someone please explain to me how do we get the following:(adsbygoogle = window.adsbygoogle || []).push({});

[P(x), L(y)]= i h(cut) P(z)

P(x) is the momentum operator with respect to x

and L(y) is the angular momentum operator with respect to y.

I have also attached the solution. I am stuck at the underlined part. I do not know how to proceed from there.
