there seem to be varying definitions of "standard form."
Since this is not my area of expertise, I searched Google under the key words "math 'standard form'" to get these possible sources:

From the information, it seems like you have already written the numbers in standard form. However, you might want to arrange them differently.
80,000 + 3,000 + 400 + 70 + 2
Even so, this seems to be the expanded form of
83,472.
I hope this helps. Thanks for asking.
