Question

what is the place value of the underlined digit?
2,487,492
4,389,024

Explanation:

For 2,487,492 (assuming the underlined digit is the first 2, but wait, looking at the number: 2,487,492 – let's check the digits. Wait, maybe the underlined is the 2? Wait, no, the number is 2,487,492. Let's parse the places. Wait, maybe the underlined digit is the 2 (the leftmost). Wait, no, maybe the first number is 2,487,492. Let's do place values.

First number: 2,487,492

Step1: Identify the underlined digit. Wait, the underlined is on the 2? Wait, the number is 2,487,492. Let's write the place values. The digits are (from right, but wait, left to right: millions, hundred thousands, ten thousands, thousands, hundreds, tens, ones). Wait, 2,487,492: the leftmost 2 is in the millions place? Wait, no: 2,487,492 is 2 million, 4 hundred thousand, 8 ten thousand, 7 thousand, 4 hundred, 9 ten, 2 one. Wait, no, let's count the digits: 2 (1st digit, millions place? Wait, 2,487,492 has 7 digits. Positions (from right, starting at 0):

Digit positions (right to left, starting at 0 for ones place):

Position 6: 2 (millions place: \(10^6\))

Position 5: 4 (hundred thousands: \(10^5\))

Position 4: 8 (ten thousands: \(10^4\))

Position 3: 7 (thousands: \(10^3\))

Position 2: 4 (hundreds: \(10^2\))

Position 1: 9 (tens: \(10^1\))

Position 0: 2 (ones: \(10^0\))

Wait, but the underlined digit is the first 2 (leftmost), so position 6, which is millions place? Wait, no, maybe the underlined is the 2 in 2,487,492. Wait, maybe the user's underlined digit is the 2 (the first digit). So place value is millions? Wait, no, 2,487,492: 2 is in the millions place? Wait, 1,000,000 is \(10^6\), so 2 * \(10^6\) is 2,000,000. So place value is millions.

Step2: For the second number: 4,389,024 (wait, the second number is 4,389,024? Wait, the underlined digit: let's check. The number is 4,389,024. Let's parse the digits. Wait, maybe the underlined digit is the 4? Wait, no, the underlined is on the 4? Wait, 4,389,024: digits are 4 (millions? No, 4,389,024 is 4 million? Wait, 4,389,024 has 7 digits. Position 6: 4 (millions: \(10^6\))? Wait, no, 4,389,024: 4 is in the millions place? Wait, 4 * \(10^6\) is 4,000,000. Wait, but maybe the underlined digit is the 4? Wait, no, the user's problem: "What is the place value of the underlined digit?" for 2,487,492 and 4,389,024.

Wait, maybe the first number: 2,487,492 – underlined digit is 2 (leftmost). So place value: millions place (2,000,000).

Second number: 4,389,024 – underlined digit is 4 (leftmost). Place value: millions place (4,000,000). Wait, but maybe the underlined digits are different. Wait, the first number: 2,487,492 – maybe the underlined digit is the 2 in the thousands place? No, the underlined is on the comma? Wait, the original image: "2,487,492" with underline on the 2 (before the comma). So 2,487,492: the 2 is in the millions place (since 2,000,000 is 2 million).

For 4,389,024: the underlined digit is 4 (before the comma), so 4 is in the millions place (4,000,000).

Wait, maybe I misread. Let's re-express:

First number: 2,487,492. Let's write the number with commas: 2,487,492. The digits are:

• 2: millions place (2 × 1,000,000 = 2,000,000)

• 4: hundred thousands (4 × 100,000 = 400,000)

• 8: ten thousands (8 × 10,000 = 80,000)

• 7: thousands (7 × 1,000 = 7,000)

• 4: hundreds (4 × 100 = 400)

• 9: tens (9 × 10 = 90)

• 2: ones (2 × 1 = 2)

So if the underlined digit is the first 2 (leftmost), place value is millions.

Second number: 4,389,024. Digits:

• 4: millions place (4 × 1,000,000 = 4,000,000)

• 3: hundred thousands (3 × 100,000 = 300,000)

• 8: ten thousands (8 × 10,000 = 80,000)

• 9: thousands (9 × 1,000 = 9,000)

• 0: hundreds (0 × 100 = 0)

• 2: tens (2 × 10 = 20)

• 4: ones (4 × 1 = 4)

So if the underlined digit is the first 4 (leftmost), place value is millions.

But maybe the underlined digits are different. Wait, the user's problem: "What is the place value of the underlined digit?" for 2,487,492 and 4,389,024. Let's assume the underlined digit…

Answer:

For 2,487,492: The underlined digit (2) is in the millions place (place value: \(2 \times 10^6 = 2,000,000\)).
For 4,389,024: The underlined digit (4) is in the millions place (place value: \(4 \times 10^6 = 4,000,000\)).

(Note: If the underlined digits are different, adjust based on the actual underline. For example, if the underline is on the 4 in 2,487,492 (hundred thousands place: \(4 \times 10^5 = 400,000\)) or the 0 in 4,389,024 (hundreds place: \(0 \times 10^2 = 0\)), clarify the underline position. The above assumes the leftmost digit is underlined.)
