Dear Student,

Please find below the solution for your asked query-

In a chemical formula, generally, the polyatomic ions in the
chemical formulae are enclosed in parentheses followed by a
subscript if more than one of the same type of polyatomic ion
exists

Now, as we can see, only one OH- ion is present in the
given compound NaOH Therefore, we don't need to add parenthesis in
this case
