Answer 1

The expanded form of the number 300,684 with only four add-ons is 300,000 + 600 + 80 + 4. This reflects the value of each digit based on its place value.

Step-by-step explanation:

The question asks to write the expanded form of the number 300,684 in a way that it is expressed with only four add-ons. The correct expanded form representing this number with only four terms would be 300,000 + 600 + 80 + 4.

To expand a number, each digit is given its value according to its place in the number. Thus, in the number 300,684:

• The digit 3 is in the hundred thousand's place, so its value is 300,000.
• The digit 6 is in the thousand's place, so its value is 600.
• The digit 8 is in the ten's place, so its value is 80.
• The digit 4 is in the one's place, so its value is 4.

Therefore, the expanded form with only four add-ons is 300,000 + 600 + 80 + 4, which corresponds to option b.
