Answer 1

Answer: 7.46 x 10-4

Explanation:You move the decimal place 4 times. For any scientific notation question in the future, look at the answer choices and beside the answer choices work it out. By working it out just take the rounded number (which in this case is 7.46) and go to the decimal and move it however many times it states in the 10 (10-4, move 4).
