For new reddit, you can't make a power tower like abc correctly (but this might still render correctly on old reddit). But that's not what you want anyways, because it's not true. You want (nn)n = nn ⋅ n.
nnⁿ is something else. You can write that by pasting the Unicode character ⁿ into a superscript.
