1. 10 to the power of 3 multiplied by 0.02 should give you an answer of 20.
2. Explanation: Since you need to move the decimal three places to the right in order to get an answer of 20, every time you move the decimal point to the right, you are multiplying the number by 10. (Example: 0.02 x 10 = 0.2) (0.2 x 10 = 2) (2 x 10 = 20).
3. Hope this helped :)
