Question 67613: This does not relate to coins, however I could not find the right place to go. I had help with a question that I had sent, #67075. Word problem with the Queen Mary. The answer was right, however my teacher marked exponent? NOt sure what she is asking. Could you please help. Greatly appreciated.
Grateful 7th grader

You can put this solution on YOUR website! Your question was related to converting a large number to scientific notation.
You have this:
The Queen Mary is a large cruise ship that has 8,123,700 cubic feet of cargo space. Express this number in scientific notation.
answer I have-8.1237x10 to the 7th.
However, your exponent is incorrect!
Stanbon answered you correctly, saying that since you must move the decimal 6 places to the left in order to get a number that is between 1 and 10, this should be 8.1237 x 10^6. Your teacher was probably indicating to you with the note "exponent" that your number was correct, but the exponent was wrong.
