Let’s break down the expression step by step! Start with the innermost parentheses: \(2 + 7 = 9\). Now, substitute that back into the expression. Next, you have: \( 9 \cdot (71 - 6 \cdot 9) + 9 \). Now calculate \(6 \cdot 9 = 54\), so it becomes: \( 9 \cdot (71 - 54) + 9 \). Now calculate \(71 - 54 = 17\), giving: \( 9 \cdot 17 + 9 \). Next, calculate \(9 \cdot 17 = 153\). Finally, add \(9\) to get: \( 153 + 9 = 162\). So, the final answer is \(162\).
