To write a number in expanded form we first need to divide it by a power of 10 so that the greatest digit is the units (it is currently the tenths)

In this case, you can divide by 0.1 to get 4.92

0.1 is the negative oneth power of ten, or 10-1. This needs to be written alongside 4.92 as a multiplication. Thus, the expanded form of 0.492 is 4.92x10-1

I believe that the above is the correct answer but for the scientific form.

The expanded form is

4*10-1 + 9*10-2 + 2*10-3

or

4/10 + 9/100 + 2/1000
