The correct Answer is:
To solve the equation \( 15.08 \times 18.02 - ? = 14^2 \), we will approximate the values involved and find the value of the question mark (?). ### Step-by-Step Solution: 1. **Approximate the Values**: - Approximate \( 15.08 \) to \( 15 \). - Approximate \( 18.02 \) to \( 18 \). - Calculate \( 14^2 \) which is \( 196 \). 2. **Set Up the Equation**: - Rewrite the equation using the approximated values: \[ 15 \times 18 - ? = 196 \] 3. **Calculate the Product**: - Calculate \( 15 \times 18 \): \[ 15 \times 18 = 270 \] 4. **Rearrange the Equation**: - Substitute the product back into the equation: \[ 270 - ? = 196 \] 5. **Isolate the Question Mark**: - Rearranging gives: \[ ? = 270 - 196 \] 6. **Perform the Subtraction**: - Calculate \( 270 - 196 \): \[ 270 - 196 = 74 \] 7. **Final Answer**: - The approximate value that will come in place of the question mark (?) is \( 74 \). ### Conclusion: The approximate value of the question mark (?) is \( 74 \).
