Quick (and simple) question: I'm writing a formula that uses parameters with a subscript, and they are squared. What is the correct way to typeset that? See below.

I fear that in (1) the $^2$ might be seen as an additional characteristic and not as "squared".

  1. $s_1^2$
  2. ${s_1}^2$
  3. $({s_1})^2$

  • Personally, I don’t think there’s wrong in writing 1. –  Apr 22 '20 at 09:33

    According to https://math.stackexchange.com/help/on-topic, questions about typesetting equations are off-topic on this site. – Martin R Apr 22 '20 at 09:36
  • I think option (3) makes it clear that you want to square $s_1$. Otherwise, maybe just write $s_1 \cdot s_1$. – StefanH Apr 22 '20 at 20:40
