Use the <sup> tag to create superscripted text. The HTML <sup> tag is used for defining subscript text like,
2<sup>3</sup> + 3<sup>2</sup> = 17
Example
You can try to run the following code to display subscripted text in HTML −
<!DOCTYPE html> <html> <head> <title>HTML sup Tag</title> </head> <body> Value of 2<sup>3</sup> + 3<sup>2</sup> = 17 </body> </html>
