Partial derivatives: find marginal utility (MU) D and F with U(D,F) = 10DF

[CHRISTMAS]

So, my utility function is U(D,F)=10DF. What is the Marginal Utility (MU) D and F?

Is this thinking correct. I would take the partial derivative of each variable, therefore:

The MU of D would be --> 10F

The MU of F would be --> 10D

The MU of D would be --> 10F

The MU of F would be --> 10D

That is what comes from the usual accepted definition.
