It's all about the charges.
Explanation:
Note that cadmium nitrate is an ionic compound, meaning the charges have to balance. You can determine this by knowing that cadmium is a metal, and nitrate is a non-metal.
You should be able to find that the charge of a cadmium ion is 2+ and the nitrate ion is 1-
This means that you need 2 nitrate molecules to balance the charge the cadmium cation creates.
From this, you get
The subscript to the right of the nitrate molecule indicates that there are two of them, which is why parenthesis are needed to be placed around the
