= 3 + .03 + .004 + .0008 + .00001 (one kind of expanded form)

= 3*1 + 0*.1 + 3*.01 + 4*.001 + 8*.0001 + 1*.00001 (another kind of expanded form)

= 3*10^0 + 0*10^-1 + 3*10^-2 + 4*10^-3 + 8*10^-4 + 1*10^-5 (expanded form using exponents)

_____

The idea of expanded form is to show the place value of each digit. These are all expanded forms. Choose the one consistent with your text or teacher's method of expression.
