Unit 1 - Objective 4 - Exponent Rules


1. A natural number power a5 = a a a a a is repeated multiplication.
2. A negative power is a reciprocal.
3. To Multiply the same base a3 a5 = a3 + 5 = a8 Add exponents.
4. To Divide the same base Subtract exponents.
5. To raise a Power to a Power (a5)3 = a5 3 = a15 Multiply exponents.

 

Examples:
  1. 105 104 = 105+4 = 10 9
  2. 3 32 = 31 32 = 31 + 2 = 33 = 3 3 3 = 27
