When we write 10⁶, the number 10 is called the base. The number 6 is the exponent or power. We say “ten to the sixth power” or just “ten to the sixth.” We call 10⁶ the sixth power of 10.

Other numbers can be written using exponents.

• 

When we write 2³, the 2 is the base and 3 is the power or exponent.

1. Name the base and the exponent in 5².
2. Name the base and the power in 3⁴.
5. Find n.
1. 4³ = n
2. 2⁵ = n
3. 6¹ = n
6. Write the following using exponents. Then find the value of n.
7. Example:
   5 5 5 5 = n
   5⁴ = 625
1. 4 4 4 = n
2. 2 2 2 2 2 2 = n
3. 8 8 8 = n
