1. Warm up Complete the table. What pattern do you see as you complete the 2 x column? What pattern do you see as you complete the 10 x column? What do you notice in the row where zero is the exponent? How are the terms 2 2 and 2 -2 related? 10 2 and 10 -2 ?

2. Negative Exponent a -n is the reciprocal of a n : Properties of Exponents Zero Exponent Examples: 4 0 =1 (-3) 0 =1 (5.14) 0 =1 A nonzero number to the zero power is 1:

3. Negative exponents move terms to the other part of the fraction. (reciprocal) Example 1: Evaluate 4 is downstairs. We will move it…

4. Example 2 x is downstairs. We will move it…

5. Example 3 -9 is upstairs. We will move it…

6. Now let’s include what we learned from last class.

7. Evaluate the expression without using a calculator.

8. Rewrite the expression with positive exponents.
