Question 7 (Mandatory) (1 point) Which of the following expresses $-\sqrt{8} \times \frac{1}{2} \sqrt{32}$ in simplest form? a) $-8 \sqrt{2}$ b) -8 c) $2 \sqrt{64}$ d) $4 \sqrt{8}$ Previous Page Next Page Page 7 of 20

Step 1 ：Simplify each square root separately. The square root of 8 can be simplified to \(2\sqrt{2}\), and the square root of 32 can be simplified to \(4\sqrt{2}\).

Step 2 ：Substitute the simplified square roots into the expression, which becomes \(-2\sqrt{2} \times \frac{1}{2} \times 4\sqrt{2}\).

Step 3 ：Multiply these together to get the final answer.

Step 4 ：The simplest form of the expression \(-\sqrt{8} \times \frac{1}{2} \sqrt{32}\) is \(-8\).

Step 5 ：Final Answer: \(\boxed{-8}\)
