Question

Quizplus · Accepted Answer

To write a number in scientific notation, we need to move the decimal point so that there is only one non-zero digit to the left of the decimal point. In this case, we move the decimal point three places to the left to get 3.45626. Then, we express this number as a decimal number between 1 and 10, multiplied by a power of 10. The power of 10 is determined by the number of places we moved the decimal point. Since we moved it three places to the left, the power of 10 is 10^3 or 1000. So, 345.626 in scientific notation is 3.45626 x 10^2. This is choice E.
