A.
To find the scientific notation of a number take that number and
move the decimal place over so that there is one digit to the left of
it. Then write that number including its new decimal location and add "x
10^" making the power the ten is raised to how many places the decimal
was moved to the left. In this case the decimal was moved 6 places to
give: 5.098 × 10^6, answer "a"
