\begin{tabular}{l} Evaluate the following expression. \\ \( \qquad[1+(16+19) \div 5] \times 3 \) \\ \hline ? \end{tabular}

To evaluate the expression \( [1+(16+19) \div 5] \times 3 \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Let's break it down step by step: 1. **Calculate the expression inside the parentheses**: \[ 16 + 19 = 35 \] 2. **Now substitute back into the expression**: \[ [1 + 35 \div 5] \times 3 \] 3. **Next, perform the division**: \[ 35 \div 5 = 7 \] 4. **Substitute this result back into the expression**: \[ [1 + 7] \times 3 \] 5. **Now, perform the addition inside the brackets**: \[ 1 + 7 = 8 \] 6. **Finally, multiply by 3**: \[ 8 \times 3 = 24 \] Thus, the final result of the expression \( [1+(16+19) \div 5] \times 3 \) is \( 24 \).
