8. Use Properties of Exponents & Add, Subtract, Multiply Polynomials GOALS: “” Algebra 2: Notes 5.1 & 5.3:

9. 5.1 Example 1: Evaluate or simplify the expressions Add, subtract, multiply, or reciprocal? Multiply powers Add, subtract, multiply, or reciprocal? Subtract powers Add, subtract, multiply, or reciprocal? reciprocal powers Power out the answer Add, subtract, multiply, or reciprocal? Multiply powersSimplify; leave positive powers Add, subtract, multiply, or reciprocal? Multiply powersreciprocal powers

10. 5.1 Example 2: Use scientific notation in real life. Iceland covers about 1.03 x 10 5 square kilometers and has approximately 2.94 x 10 5 people. About how many people are there per square kilometer? Sounds like a rate, so set it up as a rate: Simplify: divide the numbers, and subtract the powers Fill in the numbers Rewrite in Scientific or decimal whichever makes the most sense. or

11. 5.1 Example 3: Compare real life volumes. The radius of a beach ball is about 5.6 times greater than the radius of a baseball. How many times as great at the baseball’s volume is the beach ball’s volume? (Hint: solve a similar problem—square A has a side length 2 times the side length of square B. Compare the volumes.) Find volume of Square A and Square B So for something that is 2 times as big the volume is 2 3 as big. Square B with side length x Volume =x 3 Square A with side length 2x Volume=(2x) 3 =8x 3 Beach ball has a volume 175.616 times bigger than the volume of a baseball.

12. 5.3 Example 4: Add, subtract, or multiply polynomials. a. b. Change to add the opposite, and combine like terms.

13. 5.3 Example 4: Add, subtract, or multiply polynomials. c. d. Area of rectangles model. Label the sides. Find the area of each part Add the areas together, combining like terms. Do the distributive property multiple times. Combine like terms.
