When a subscript is placed outside parentheses in mathematical notation, it typically indicates that the subscript applies to the entire expression within the parentheses rather than to a specific variable or element inside. For example, if you see ( A_{(i)} ), it means that the entire expression ( A ) is being indexed by ( i ). This notation is often used in contexts like matrices or sequences where the entire group or set of values is being referenced collectively.
The distributive property.
Distributive Property
The distributive property is a property for multiplying with parentheses. It states that a(b+c)=ab+ac. The means that 3(x+2)=3x+6, for example. Basically, the distributive property says you must multiply everything within the parentheses by the number outside the parentheses.
Determine the GCF .If it is 1 then continue with the next step but if it is a number such as three then remove that number and divide each monomial by that number and put the polynomial within a set of parentheses with the GCF on the outside of the parentheses

The subscript outside the parentheses: (H2SO4)2
The subscript outside the parentheses applies to all the elements within the polyatomic ion. It indicates how many of the entire polyatomic ion are present in the compound.
To count atoms on a worksheet, first identify the chemical formulas present. For each element in the formula, note the subscript that follows it, which indicates the number of atoms of that element. If there is no subscript, it means there is one atom of that element. For compounds with parentheses, multiply the subscript outside the parentheses by the subscripts inside to find the total number of atoms for each element.
When counting atoms in a chemical formula, each element's symbol is followed by a subscript that indicates the number of atoms of that element present in the molecule. If there is no subscript, it is understood to be one. Parentheses indicate that the atoms within them are multiplied by the subscript outside the parentheses. For example, in the formula ( \text{Ca(OH)}_2 ), there is one calcium atom, two oxygen atoms, and two hydrogen atoms.
To effectively read chemical formulas with parentheses, first identify the elements within the parentheses and the number of atoms of each element. Then, apply the subscript outside the parentheses to all elements inside. This helps clarify the composition of the compound and ensures accurate interpretation of the formula.
A subscript following a set of parenthesis in a chemical formula indicates that the entire group enclosed in the parenthesis is to be multiplied by the subscript outside the parenthesis. This is used to show the number of times a group of atoms or molecules is repeated in the compound.
The subscript tells you how many atoms of a certain element are in the representative particle of that substance. For example, H2O means 2 hydrogens and 1 oxygen. (The absence of a subscript means there's just 1.) The subscript only applies to the element immediately before it, unless the subscript occurs outside a set of parentheses, in which case it applies to everything inside the parentheses.
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
Parentheses are used in chemical formulas to indicate the number of atoms or groups of atoms that are enclosed should be multiplied by the subscript outside the parentheses. In the case of Al(OH)3, it indicates that there are three hydroxide (OH) groups for each aluminum (Al) atom in the compound aluminum hydroxide.
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
Parentheses are used in ionic compound formulas when multiple polyatomic ions are present. The parentheses are used to indicate a subscript that applies to all the elements inside the parentheses. For example, in the formula for calcium nitrate (Ca(NO3)2), the parentheses indicate that the nitrate ion (NO3) has a subscript of 2.
