How do you write 4408730 in expanded form

There are different versions of "expanded form." Pick the one that matches your requirements.

4408730 = 4000000 +400000 +0 +8000 +700 +30 +0

4408730 = 4·1000000 +4·100000 +0·10000 +8·1000 +7·100 +3·10 +0·1

4408730 = 4·10⁶ +4·10⁵ +0·10⁴ +8·10³ +7·10² +3·10¹ +0·10⁰

I like the last one (with exponents) because it shows clearly how the place value is a power of 10. If you keep going to the right of the decimal point, the exponents continue to get smaller (increasingly negative). This also gives you a clue as to how numbers would be translated to other number bases. (Replace 10 with the number base of your choice.) It also shows you how numbers can be written in scientific notation.
