The HTML element <sup> can be used to put a text in this form:

2<sup>3</sup>

Vira: 23.

Alternatively, you can use the unicode characters for superscript (although only a few of them are supported):

2&#x00B3;

2³ In this case it would be necessary to map each number of 0 to 9 to his code point correspondent.

If you have this value in a string as you put it can do so:

var x = '2,5';
var partes = x.split(',');
var htmlString = partes[0] + '<sup>' + partes[1] + '</sup>';
