The correct Answer is:
To solve the equation \( \sqrt{2401} + \sqrt{3969} - \sqrt{3136} = 32 + ? \), we will follow these steps: ### Step 1: Calculate \( \sqrt{2401} \) We need to find the square root of 2401. - \( \sqrt{2401} = 49 \) because \( 49^2 = 2401 \). ### Step 2: Calculate \( \sqrt{3969} \) Next, we calculate the square root of 3969. - \( \sqrt{3969} = 63 \) because \( 63^2 = 3969 \). ### Step 3: Calculate \( \sqrt{3136} \) Now, we find the square root of 3136. - \( \sqrt{3136} = 56 \) because \( 56^2 = 3136 \). ### Step 4: Substitute the values into the equation Now we substitute these values back into the equation: \[ 49 + 63 - 56 = 32 + ? \] ### Step 5: Simplify the left side Now we simplify the left side: - \( 49 + 63 = 112 \) - \( 112 - 56 = 56 \) So, we have: \[ 56 = 32 + ? \] ### Step 6: Solve for ? To find the value of ?, we subtract 32 from both sides: \[ ? = 56 - 32 = 24 \] Thus, the value that comes in place of the question mark (?) is **24**. ### Final Answer: The answer is \( ? = 24 \). ---
