Something like (C10H8O4)n? (This is the formula for the plastic a Coke bottle is made of.) It means there are multiple instances of whatever group is inside the parentheses.

How should more than one polyatomic ion be indicated a chemical formula?
More than one polyatomic ion should be indicated in a chemical formula by putting parentheses around the atoms in the ions and then adding a subscript.
Why do you put parentheses around a polyatomic ion?
You use parentheses to represent that a polyatomic ion is used more than once as a whole. For example Ba(NO2)2. It is NO2 that is used twice because Ba has a 2+ charge and NO2 has a -1 charge. So you need 2 NO2 to make the formula equal 0. So you use the parentheses to represent you are using 2 NO2

How should more than one polyatomic ion be indicated in a chemical formula?
One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
