1. The problem is to evaluate the expression $8.8 \times \sqrt{325.6}$. 2. Recall that the square root function $\sqrt{x}$ gives the number which when squared equals $x$. 3. First, calculate $\sqrt{325.6}$. 4. Using a calculator or approximation, $\sqrt{325.6} \approx 18.05$. 5. Now multiply $8.8$ by $18.05$: $$8.8 \times 18.05 = 158.84$$ 6. Therefore, the value of $8.8 \times \sqrt{325.6}$ is approximately $158.84$.
