Let's break it down step by step for clarity! First, calculate the square root: \( \sqrt{16} = 4 \). Then, find \( 9^2 = 81 \) and \( 3^3 = 27 \). Now substitute these values into the expression: \[ (4 + \frac{81}{27}) - 7 \] Next, simplify \( \frac{81}{27} = 3 \). Now the expression becomes: \[ (4 + 3) - 7 \] So, \( 4 + 3 = 7 \). Finally, \( 7 - 7 = 0 \). The final answer is \( 0 \).
