what is subscripted text and superscripted text

Question

how can I be helpful by these type of text style.....

Answer 1

when we write x square (in maths) 2 is superscript
and when we write o 2 (in them) 2 is subscript

Answer 2

for the word in which you use it, and the "sub" tag down , "sup" moves up to the label. "px" you can do so using.

Answer 3

For most purposes, you can use the  tag to create super script text and to create sub-script text. See examples below:

Code : x^x+1
Result : xx+1
Code :x_i+1
Result : xi+1
those x+1 and i+1 are called superscript and subscript respectively.
