Unit 1  Objective 4  Exponent Rules
1. A natural number power  a^{5} = a · a · a · a · a  is repeated multiplication. 
2. A negative power  is a reciprocal.  
3. To Multiply the same base  a^{3} · a^{5} = a^{3 + 5} = a^{8}  Add exponents. 
4. To Divide the same base  Subtract exponents.  
5. To raise a Power to a Power  (a^{5})^{3} = a^{5 · 3} = a^{15}  Multiply exponents.
