Exponents Issue

Code:

x^(1/9)*(x*x^(1/3))^(1/6)

to be simplified to

Code:

x^(1/3)

, but the calculator does not simplify it (tried collect, simplify functions with no effect). TI-89 Titanium and TI-Nspire both calculators simplify it.
Any ideas?

A funny try in the middle of the night:

Code:

#cas
expcollect(f):=
BEGIN
  LOCAL g,s,v;
  v:=mat2list(algvar(f));
  s:=SIZE(v);
  v:=head(mat2list(v(s)));
  g:="'solve(y_="+f+","+v+")'";
  g:=expr(g);
  f:="'solve("+v+"="+g+",y_)'";
  RETURN expr(f);
END;
#end
