1. Aim: How do we work on the expression with negative or zero exponent?
Do Now: simplify: 1. 2.
If x = 2 and y = 3, evaluate 4. 3.
HW: Worksheet

2. Another way
Therefore,
Therefore, x3y3 = (xy)3

3. Laws of Exponents Multiplication Law: xa · xb = xa+b
Division Law: xa  xb = xa-b
Power law: (xa)c = xac
Power-of-a-Product Law: (xy)a = xaya
Power-of-a-Quotient Law:
6. Zero Power: x0 = 1, x  0
7. Negative Exponent:
