Show that the expectation value of Lz is -2h for the radial wavefunction Y2,-2. ??? Can someone do this?

Use the matrix representation for the basis l=2.

Remember that
[tex]
\mathbf{L_z} = m\hbar
[/tex]

That's not how it works here. It's against the forum rules to provide solutions, and you need to show some attempt at solving the problem before you'll get help here.

The wavefunction is normalized. Radial function cannot be Y, that's the spherical harmonics. Just apply the expected value in the ket-bra notation
