  I'm afraid I have unhappy news for you.  There is *no* way of simplifying the values you ask about without going to an approximation.  Coming from a simplification of symbolic equations, they will already have been reduced as far as is possible if they are to remain exact.  Of course you can always enter them into the non-symbolic part of matlab to get its best approximation with 'double' values using 'vpa', but you must realize these are only approximations.
