sorry to ask such a simple question...

i have a very long espression of the form

 A[k, r]( B[k,r] + C[k,r] + blah blah blah)
             D[k, r]

it took me awhile to figure out how to decompose this (i was trying to use
Apart.  instead, ExpandAll seemed to do the trick).

but i'm still seeing terms that look like:

   k r cos(k r)
   \sqrt{k} r^{3}

no amount of coaxing seems to make Mathematica want to reduce this to:

   \sqrt{k} \cos(k r)

FullSimplify just undoes ExpandAll and puts everything over a common
denominator.   i want separate terms which are fully reduced.

how can i have Mathematica aggresively reduce these individual terms?
