Is it as an annotation on a plot? If so, you can do something like:

figure('color','white','units','inches','position',[2 2 4 6.5]);
axis off
h(1) = text('units','inch', 'position',[.2 5], ...
'fontsize',14, 'interpreter','latex', 'string',...
['$$\sqrt[3]{x}$$']);

Yes. At the legend :)

Thanks.

PS. They are generalized 'sqrt'...
