Ms. Golden says that 9.004 × 10^-4 is equivalent to 0.09004.

Mr. Sampson says she made a mistake.

What was the mistake?

• The answer should have been a large number, not a small one

• She should have rounded her answer to 0.09000

• The decimal point should move two more spaces to the left

• The decimal point should have stayed where it was and we just add zeroes to the ends
