Question

What is the product of 8.2 × 10/\9 and 4.5 × 10/\-5 in scientific notation?

36.9 × 10/\-45
12.7 × 10/\4
3.69 × 10/\5
3.69 × 10/\14

Answer 1

3.69 x 10^5, because the original answer is 369000, but scientific notation requires that you have your answer between 1-10. Just move 5 places to the left, which means your power of 10 will be positive.

Answer 2

To make things easier for you, the correct answer is C: 3.69 × 10^5
