9.846 x 10^12

Answer 2

A scientific notation is always a way to shorten long numbers into a smaller, more compact number. Scientific notations all have a decimal point after ONE number, so B and D are out. The answer would be 9.846*10^12 because we will have to count from the decimal point to the last number,
