EXAMPLE 4 Multiplying Numbers in Scientific Notation Find the product (4.5 10 3 ) (6.3 10 7 ). = 4.5 6.3 10 3 10 7 (4.5 6.3) (10 3 10 7 ) = = 28.35 10 10 = 2.835 10 1 10 10 2.835 10 11 = Product of powers property Write 28.35 in scientific notation. Product of powers property Commutative property of multiplication Associative property of multiplication

GUIDED PRACTICE for Example 4 Write the product in scientific notation (1.25 10 6 ) (7.6 10 12 ) 17. = 9.5 10 18

GUIDED PRACTICE for Example 4 Write the product in scientific notation 4.52 10 11 = 18. (8 10 6 ) (5.65 10 4 )
