Which of the following equations are true? (choose 2) Responses A (3.8 × 108)(4.48 × 106) = 1.7024 × 1015(3.8 × 10 8 )(4.48 × 10 6 ) = 1.7024 × 10 15 B 1.16 × 109 = 1.36 × 105 8.5 × 107 1.16 × 10 9 = 1.36 × 10 5 8.5 × 10 7 C 9 × 105 = 1 8 × 106 9 × 10 5 = 1 8 × 10 6 D (5.5 × 103)(4.1 × 102) = 22.55 × 105(5.5 × 10 3 )(4.1 × 10 2 ) = 22.55 × 10 5 E (6 × 102) × (4 × 10-2) = 24 × 105
The true equations are A and D:
A. (3.8 × 108)(4.48 × 106) = 1.7024 × 1015
D. (5.5 × 103)(4.1 × 102) = 22.55 × 105
