Answer:
The correct answer is A) 3.712 x 10^7
Step-by-step explanation:
To find any number in scientific notation, you have to move the decimal place until the number is in between 1 and 10. Then, count the amount of places that it moves and use that as the exponent. If it moves to the left it is positive. If it moves to the right it's negative.
So, since we move this to the left 7 times, then we make it positive 7.
