Answer 1

Why not go ahead and actually multiply 9.1 by 101? Then you'll be in a much better position to select the right answer to this question.

Answer 2

this is really common sense

Answer 3

10 is power 1

Answer 4

Ohh. So anything you take the power to 1, is equal to itself, like this: \[x^1=x\]

Answer 5

Because it is the amount of times you multiply the number by itself, so in this case it's just the number itself :)
