1. The problem asks to write 8.07 million in expanded notation. 2. First, understand that 1 million equals 1,000,000. 3. So, 8.07 million means $8.07 \times 1,000,000$. 4. Multiply: $$8.07 \times 1,000,000 = 8,070,000$$ 5. Now, write 8,070,000 in expanded notation by breaking it down by place value: $$8,000,000 + 70,000$$ 6. This shows the value of each digit in the number clearly. 7. Therefore, 8.07 million in expanded notation is: $$8,000,000 + 70,000$$
