Question

Pls help!! I’m confused

Answer 1

3.105 x 10 to the 7 power because you move right 7 times

Answer 2

3.105 x 10^-7

You have to move the decimal point until it is between two numbers that is not 0. Since you have to move it seven times to the right it is 10 to the power of -7. Negative goes right positive goes left. After you move the decimal to the appropriate place, that will be your new number. Then you just put everything together.
