Name: Sample Work for Algebra 1B: Submit in the Sample Work Drop Box in Lesson 8! Please fill in all blanks; answer every question and SHOW your work for the 2 problems listed. Unit 1: Exponents and Exponential Functions Lesson 1: Zero and Negative Exponents Objective: Can you simplify expressions involving zero and negative exponents? 1. Property of negative exponent:__ Negative exponents indicate reciprocation, with the exponent of the reciprocal becoming positive. You may want to think of it this way: unhappy (negative) exponents will become happy (positive) by having the base/exponent pair “switch floors”! ____________________________________ 2. Property of zero exponent:___ Any number raised to the zero power is equal to “1”._______________________________________ Practice work: Read pp. 414-417 Complete p. 417, 9-35 odd in your notebook. 3.

Lesson 2: Scientific Notation Objective: Can you write numbers in scientific and standard notation? Can you compare and order numbers using standard notation? 5. In your own words, describe scientific notation: scientific notation is a way to put really big numbers in to smaller forms that way you van right it in a decimal form 6. Why is it important to understand how to write numbers in scientific notation? Some numbers are so huge that you have to put it in a smaller form but you dont know how. Thats why we are taught to put numbers that are to big in scientific notation that way we dont have to write the who entire number that is really big and me sarcastically take forever to write Practice work: Read pp. 420-423 Complete p. 424, 11-34 and 40-47 in your notebook. 7.
