Exponents
Exponents are a way of representing repeated multiplication of the same number. The exponent tells us how many times the base number is multiplied by itself.
Basic Notation
The basic notation for expressing exponents is:
an
Where 'a' is the base and 'n' is the exponent.
Examples
For example, 23 means 2 multiplied by itself 3 times, which equals 8 (2 * 2 * 2).
Another example is 52, which means 5 multiplied by itself 2 times, equaling 25 (5 * 5).
Rules
There are some important rules for working with exponents:
- Product Rule: am * an = am+n
- Quotient Rule: am / an = am-n
- Power Rule: (am)n = am*n
- Zero Rule: a0 = 1
Practice Problems
Simplify the following expressions:
- 34
- 25 / 23
- (42)3
Answer Key
- 34 = 81
- 25 / 23 = 32
- (42)3 = 4096
