MaplePrimes - answers and comments on Question, simplify, but not

No "freeze" for integers and rationals.

Unfortunately, freeze doesn't work for integers and rationals. But subs does work. So the following kludge does it:

ex:= 16^j/16;
exf:= subs(_x= 16, simplify(subs([1/16= 1/_x, 16= _x], ex)));

It sure looks ugly though.

How about this?

As far as I remember it, a similar topic was recently considered. Unfortunately, I can't find references in a short time.

y := 16^j/16:
subs(16=z,1/16=1/z,y):
combine(%,power,symbolic):
subs(z=16, %);

I now see that that is essentially Carl's approach, but with ?combine,power instead of simplify. Hmm. A simpler approach, then, is

y := 16^j/16:
subs(k=j-1,simplify(subs(j=k+1,y)));

It's not so simple. You used 12 instead of 16. Try it with 16.

@Carl Love for the indication of my inaccuracy.
