Laws of indices
Indices are a useful way expressing large numbers in a simple way. They also provide us with many useful properties for manipulating them using what are called the Law of Indices.There are six laws of indices. They are as follows:
1. Product Law:
To multiply expressions with the same base, we copy the base and add the indices.For example,
2. Quotient Law:
To divide expressions with the same base, we copy the base and subtract the indices.
3. Root Law:
4. Zero Law:
Any number, except 0, whose index is 0 is always equal to 1, regardless of the value of the base.
5. Power Law:
To raise an expression to the nth index, we copy the base and multiply the indices.
6. Negative Law:
With the help of these laws, we can solve any kind of problems related to Laws of Indices.

- It includes every relationship which established among the people.
- There can be more than one community in a society. Community smaller than society.
- It is a network of social relationships which cannot see or touched.
- common interests and common objectives are not necessary for society.
