1. A scientific notation is where you multiply any number by a power of 10 (negative or positive or neutral).

2. This is incorrect, because 3.825*10^6 is actually 3,825,000. The correct answer is 3.825*10^5.

3a) The power is supposed to be negative, since the number is decreasing, not increasing. It is 4.25*10^-5. 3b) The processes are alike in the way that they all have a number being multiplied by a power of 10. They are all different in the way that some numbers can be decimals, and some powers can be negative powers.
