Lesson 57 Warm-Up:
Use the figure below to answer #1 & #2.
1) Name one pair of alternate interior angles.

2)   If the m a is 120 degrees, what is the
     measure of f?
                          a b
                          d c
                      e f
                     h g

3)   Simplify:     x9 y
                   x8 y

4)   Simplify:     2x2 - 3x - x2 + 5

5)   Graph y = x - 2 on a coordinate plane.




                                                 2
Lesson 57:

FYI...Remember:

   --multiplying & the "bases" are the same - add the exponents
   --dividing & the "bases" are the same - subtract the exponents




                                                                    3
Lesson 57 Examples:
Find each product or quotient.
A) (4 X 1010)(2 x 10-6)




B) (1.5 x 10-5)(3 x 10-2)




                                 4
C) (7.5 x 10-3)(2 x 10-4)




D) (9.2 x 10-4)(2 x 107)




                            5
E)   (7.5 x 105)
     (3 x 10-2)




F)   (1.2 x 10-8)
      (3 x 10-4)
