The correct Answer is:
To solve the equation \( (19)^2 - (3)^3 - \sqrt{676} + 16 = (? )^2 \), we will follow these steps: ### Step 1: Calculate \( (19)^2 \) \[ (19)^2 = 361 \] ### Step 2: Calculate \( (3)^3 \) \[ (3)^3 = 27 \] ### Step 3: Calculate \( \sqrt{676} \) \[ \sqrt{676} = 26 \] ### Step 4: Substitute the calculated values into the equation Now, we substitute the values we calculated into the equation: \[ 361 - 27 - 26 + 16 = x^2 \] ### Step 5: Perform the arithmetic operations First, calculate \( 361 - 27 \): \[ 361 - 27 = 334 \] Next, subtract \( 26 \): \[ 334 - 26 = 308 \] Finally, add \( 16 \): \[ 308 + 16 = 324 \] ### Step 6: Set the equation equal to \( x^2 \) Now we have: \[ 324 = x^2 \] ### Step 7: Solve for \( x \) To find \( x \), we take the square root of both sides: \[ x = \sqrt{324} = 18 \] ### Final Answer Thus, the value that replaces the question mark (?) is: \[ \boxed{18} \]
