Question 1143591
.


From your post, two things are UNCLEAR:


<pre>
    (a)  where the symbol " √ " ends;

and

    (b) what the symbol  " — "  (long dash, as I see it) means.
</pre>


For &nbsp;(a), &nbsp;use parentheses to make your formulas &nbsp;UNAMBIGUOUS.


For &nbsp;(b), &nbsp;use the &nbsp;STANDARD &nbsp;mathematical symbols.
