Homework Statement
##(\hat A \times \hat B)^*=-\hat B^* \times \hat A^*##
Note that ##*## signifies the dagger symbol.
Homework Equations
##(\hat A \times \hat B)=-(\hat B \times \hat A)+ \epsilon_{ijk} [a_j,b_k]##
The Attempt at a Solution
Using as example ##R## and ##P## operators:
##(\hat R \times \hat P)^*_i=-(\hat P \times \hat R)^*_i+ \epsilon_{ijk} [Y,P_z]##
##(\hat R \times \hat P)^*_i=-(\hat P \times \hat R)^*_i##
##(\hat R \times \hat P)^*=-\hat P^* \times \hat R^*##
