An exponent is a number written above and to the right side of a value or number in math. The value or number is called the base, and the expression is read out as;
"Base raised to the power of exponent."
An example is given below;

In this example, 10 is the base and 3 is the EXPONENT.
The expression is now read out as,
"10 raised to the power of 3"
Note that even unknown values (such x as we commonly use in math) can also be an exponent or base. For example, we can have;

So basically, an exponent indicates the number of times a number is used to multiply itself.
 
        
             
        
        
        
Answer:
A ∩ B = {12}
Step-by-step explanation:
What are the possible even outcomes?  
Assuming the number cubes are 1-6, 
our possible outcomes run from 2-12, but we are looking for even rolls, so A={2,4,6,8,10,12}.   
How many of those are divisible by 3?  B={12}.  
We are looking for what is in common between these, so
 A ∩ B= {12}
