(In reply to re(2): one possible choice
by Ady TZIDON)
I'm sure I had it written down somewhere (probably shredded it) but didn't include it in my spreadsheet, possible when I allowed myself 5 digits. Thanks.
But to answer your question re the radical sign.
Heading the text edit box which we use to post comments is a string of format buttons. The second which bears the images π and Σ offers you a small set of symbols which include both those symbols and the radical, press the button and select the symbol required.
