When a number is repeatedly multiplied by itself, it is represented by an exponent in mathematics. An exponent indicates the number of times a base number is multiplied by itself. It is represented by a tiny figure, known as the exponent, that is placed above the base. 

Example: 3^4= 3*3*3*3= 81 

So, in this example we can see that the number 3 is the Base, and the number 4 is the Exponent.  

Note: You need to know what your integer rules are.  

Exponents have several important properties that help simplify calculations and expressions involving powers. Here are the properties of exponents: 

1. Product Rule 

2. Quotient Rule 

3. Power of a Power Rule 

4. Power of a Product Rule 

5. Power of a Quotient Rule 

6. Zero Exponent  

7. Negative Exponent
