Question

Write 6,004,720,080 in expanded form?

Answer 1

There are different kinds of "expanded form", so I’ll give you the two I think are the most common.
Written out this would be six billion, four million, seven hundred and twenty thousand, eighty.
In notation form it would be 6,000,000,000 + 4,000,000 + 700,000 + 20,000 + 80.

Answer 2

6,000,000,000+4,000,000+700,000+20,000+80=6,004,720,080
