Course 34-2Look for a Pattern in Integer Exponents Your Goal:Simplify expressions containing integer exponents.

Course 34-2Look for a Pattern in Integer Exponents2 Zero Power The zero power of any number except 0 equals 1.100 = 0

Course 34-2Look for a Pattern in Integer Exponents4 Negative Exponents Any number or variable (except 0) with a negative exponent means move that number or variable to the opposite place of the fraction. 5 = -3

Evaluate 1/x3 How would you solve this one?The x has a negative exponent so move it from the bottom of the fraction to the top.Course 34-2Look for a Pattern in Integer Exponents10

Course 34-2Look for a Pattern in Integer Exponents12Negative Exponents (MOVE IT MOVE IT!): Any number except 0 with a negative exponent equals its reciprocal with the opposite exponent (If its on top, put it on bottom of the fraction. If its on bottom, put it on top of the fraction.) Zero Power: The zero power of any number except 0 equals 1.
