Size of root symbol

Size of root symbol

[Bruce Horrocks via ntg-context]

Is there a simple way to get both root signs in this MWE to be the same size?

\starttext
\startformula
\sqrt[3]{4n} \ne \sqrt[3] {n}
\stopformula
\stoptext

Thanks.

Make the quantities whose roots are being taken to be of the same size.

\starttext

% The simplest solution:
\startformula
\sqrt[3]{4n} \ne \sqrt[3] {\vphantom{4} n}
\stopformula

% More general
% \strut = \vphantom{(}, which is too big
\startformula
\sqrt[3]{\strut 4n} \ne \sqrt[3] {\strut n}
\stopformula

% We can define our own phantom sizes. You can play around with the numbers.
\define\filler{\vrule width 0pt height 2ex depth 0.3ex \relax}
\startformula
\sqrt[3]{\filler 4n} \ne \sqrt[3] {\filler n}
\stopformula

\stoptext

This is for Aditya to think about

\starttext

\unprotect

\defcsname\??mathradicalalternative Mine\endcsname#1%
   {\csname\??mathradicalalternative\v!normal\endcsname
      {\synchronizestrut{\mathradicalparameter\c!strut}\strut#1}}

% \defcsname\??mathradicalalternative Mine\endcsname#1%
%   {\rootradical
%      {\currentmathradicaldegree}
%      {\synchronizestrut{\mathradicalparameter\c!strut}\strut#1}}

\protect

\definemathradical[MyRoot] [strut=cap,alternative=Mine]
\definemathradical[MyRootX][strut=yes,alternative=Mine]

\startformula
\sqrt[3]{4n} \ne \sqrt[3] {\vphantom{4} n}
\stopformula

\startformula
\MyRoot[3]{4n} \ne \MyRoot[3] {n}
\stopformula

\startformula
\MyRootX[3]{4n} \ne \MyRootX[3] {n}
\stopformula

\startformula
\sqrt[3]{\strut 4n} \ne \sqrt[3] {\strut n}
\stopformula

\stoptext

we can have strut but also think of enforcing ht / dp

(or we can have minima but that i'd rather add some options to the 
engine - we already have some but i never came to apply them yet)

Thanks Aditya, the \vphantom solution works for me -> now Wikified.
