Quizplus · Accepted Answer

To convert a number to scientific notation, we want to express it as a number between 1 and 10 multiplied by a power of 10. In this case, we can move the decimal point five places to the left to get 1.23, and we need to multiply by 10^5 to account for the five places we moved the decimal point. This gives us 1.23 × 10^5, which matches option B.
