Reply To: A Function Displayed as a Superscript with no Variable Attached

I agree with the transcriber that a superscripted abbreviated function name that does not have an argument [letter, number, or expression following and paired with the function name and printed at the same level] and is followed by material on the base line should be followed by a baseline indicator.

In other words, a baseline indicator is appropriate following the "ln" in the superscript of the example included.

Thank you for your time and for the question.
