**can anyone help?? in quantum mechanics commutator prove [L^x,L^y] = ihL^z**

given

:L^x =(y^(pz)^-z^(py)^)

:L^y =(z^(px)^-x^(pz)^)

:L^z =(x^(py)^-y^(px)^) where ^ is just showing its operator

prove comutator [L^x,L^y] = ihL^z

I am swamped at every hurdle and can't seem to get my head around this question to find the answe of ihL^z . any help would be very much appreciated
