In scientific notation, the number is written as a decimal greater than or equal to 1 and less than 10, multiplied by a power of 10. To convert 478 to scientific notation, we move the decimal point to the left until the first nonzero digit is to the left of the decimal point. This gives us 4.78. We then count the number of places we moved the decimal point, which is 2. Thus, the number in scientific notation is 4.78 x 10^2.
