Answer: [tex]1.10^{3} + 2.10^{2} + 7.10^{1}[/tex]
Step-by-step explanation: Expanded form is a way of writing numbers. It is useful because it shows the value of each digit.
In this case, the number is 1270.
It can be rewritten as:
1270 = 1000 + 200 + 70
This is its expanded form. To add exponents, we have to use cientific notation:
1270 = 1.10³ + 2.10² + 7.10¹
This is the expanded form with exponents.
