Final answer:
The expanded form of 2,701 is 2,000 + 700 + 1, illustrating the value of each digit according to its place value. The digit '2' represents 2,000 because it's in the thousands place, '7' represents 700 from the hundreds place, and '1' is simply 1 from the ones place.
Step-by-step explanation:
The expanded form of a number is a way of writing out the number to show the value of each digit. For the number 2,701, the expanded form would be written as follows:
2,000 + 700 + 1
This shows the value of each place in the number. The digit '2' is in the thousands place, so it's worth 2,000. The digit '7' is in the hundreds place, so it's worth 700. There are no tens, and there's a '1' in the ones place, worth 1.
Remember, when a calculator gives a result that includes significant figures beyond what your original numbers justified, round the result to the nearest place that makes sense based on the original numbers you were working with.
