Answer 1

If you multiplied 9.46 by 10, the decimal place would move to the right by one digit to make 94.6. If you multiplied 9.46 by 10^2 (or 100), the decimal place would move 2 digits, making 946. Here we multiply by 10^7, so the decimal place moves over 7 digits, making C the answer. If you need to move the decimal over more digits than you have digits to begin with, each additional digit is a zero.
