1. What is the small sized number above and to the right of a base number called?
   
   An exponent
   
   
2. What does 7² mean?
   
   7² means 7 x 7, or 7 squared or 7 to the second power. When you carry out the operation, you get 49 (7² = 49).
   
   
   
3. What does 3³ mean?
   
   3³ means 3 x 3 x 3, or 3 cubed or 3 to the third power. When you carry out the operation, you get 27 (3³ = 27).
   
   
4. Rewrite 6 x 6 x 6 x 7 using an exponent.
   
   6³ • 7
   
   
5. Rewrite 42 x 42 x 6 x 6 using exponents.
   
   42² • 6²
   
   
6. Rewrite 50 x 50 using an exponent.
   
   50²
   

In the following, multiply out the factors to find the value.

7. 12² = 144
   
   
8. 10³ = 1000
   
   
9. 6⁴ = 1296
   
   
10. 4² • 5³ = 2000
    
    
11. 1000² = 1,000,000
    
    
12. 6² • 4³ = 2304
    
    
13. 2² • 6² • 7² = 7056
    
    
14. 15² • 10² = 22500
    
    
15. 1³ = 1
