The answer is indeed 2.37x10^6
Why? You’ll always want your decimal to be to the right of your first number and everything else behind it, and so once you’ve place your decimal in between 2 and 7 you’ll need to count how many places you moved
(unless it were to be like this 000,073,2)
Which in this case your first number would be 7 and you’ll count backwards from there to get your answer
