Write down the value of the underlined digits. \( \begin{array}{lll}345,67 & \text { b. } 12,56 \underline{8} & \text { c. } 8 \underline{234,500} \\ 7434 \underline{5}, 064 & \text { f. } \underline{9876,341} & \text { g. } \underline{0} 014\end{array} \)

To find the value of the underlined digits in each case, we will analyze each number and identify the place value of the underlined digit. 1. **b. \( 12,56 \underline{8} \)**: The underlined digit is 8, which is in the units place. Therefore, its value is \( 8 \). 2. **c. \( 8 \underline{234,500} \)**: The underlined digit is 2, which is in the thousands place. Therefore, its value is \( 2 \times 1000 = 2000 \). 3. **d. \( 7434 \underline{5}, 064 \)**: The underlined digit is 5, which is in the tens place. Therefore, its value is \( 5 \times 10 = 50 \). 4. **f. \( \underline{9876,341} \)**: The underlined digit is 9, which is in the millions place. Therefore, its value is \( 9 \times 1000000 = 9000000 \). 5. **g. \( \underline{0} 014 \)**: The underlined digit is 0, which is in the thousands place. Therefore, its value is \( 0 \times 1000 = 0 \). Now, summarizing the values of the underlined digits: - b: \( 8 \) - c: \( 2000 \) - d: \( 50 \) - f: \( 9000000 \) - g: \( 0 \)
