Question: radnormal

I have found this problem somewhere in a math forum: somebody wanted to simplify this expression ( I write it in maple syntax:, this was not a maple forum):

a:=(1253*sqrt(2)-963*sqrt(3))^(1/3)+(26209+10500*sqrt(6))^(1/4);

They tried with the simplify command of maple, but it didn't work, and they tried with Fullsimplify command of the other famous math program , and it worked. ( I haven't tried it.) The conclusion was that Maple couldn't do this job.

Actually Maple can do this job with radnormal:

radnormal(a);

14*2^(1/2)

I tried it with simplify(a, radical)  etc. but it ddidn't work.

I think, it would be nice if the simplify command can do this job,  because many people who are not experts in maple  don't know radnormal and many other useful maple commands.
