The correct Answer is:
To solve the equation \( \sqrt{441} \text{ of } 15 \div 3 + 4 = ? \), we will follow the order of operations (commonly known as BODMAS/BIDMAS rules). Let's break it down step by step: ### Step 1: Calculate \( \sqrt{441} \) The first step is to find the square root of 441. \[ \sqrt{441} = 21 \] ### Step 2: Replace \( \sqrt{441} \) in the equation Now, we can replace \( \sqrt{441} \) with 21 in the equation. \[ 21 \text{ of } 15 \div 3 + 4 \] ### Step 3: Calculate \( 21 \text{ of } 15 \) The term "of" in this context refers to multiplication. Therefore, we multiply 21 by 15. \[ 21 \times 15 = 315 \] ### Step 4: Replace the multiplication result in the equation Now, we replace the multiplication result back into the equation. \[ 315 \div 3 + 4 \] ### Step 5: Perform the division Next, we divide 315 by 3. \[ 315 \div 3 = 105 \] ### Step 6: Replace the division result in the equation Now, we replace the division result back into the equation. \[ 105 + 4 \] ### Step 7: Perform the addition Finally, we add 4 to 105. \[ 105 + 4 = 109 \] ### Conclusion Thus, the approximate value that should come in place of the question mark is: \[ \boxed{109} \]
