Answer 2

To simplify the expression \( \sqrt[3]{16xy^6} \), we can break it down into its prime factors and simplify accordingly.

First, let's rewrite \( 16 \) and \( y^6 \):

1. \( 16 = 2^4 \)
2. \( y^6 = (y^2)^3 \)

Now, we can rewrite the expression:

\[
\sqrt[3]{16xy^6} = \sqrt[3]{2^4 \cdot x \cdot (y^2)^3}
\]

Applying the property of radicals, we can separate this into two parts:

\[
\sqrt[3]{2^4} \cdot \sqrt[3]{x} \cdot \sqrt[3]{(y^2)^3}
\]

We know that \( \sqrt[3]{(y^2)^3} = y^2 \). Now for \( \sqrt[3]{2^4} \), we can simplify it:

\[
2^4 = 2^3 \cdot 2^1 \implies \sqrt[3]{2^4} = 2 \cdot \sqrt[3]{2}
\]

Putting it all together, we have:

\[
\sqrt[3]{16xy^6} = 2 \cdot \sqrt[3]{2} \cdot y^2 \cdot \sqrt[3]{x} = 2y^2 \sqrt[3]{2x}
\]

That means the simplified form of the original expression is:

\[
2y^2 \sqrt[3]{2x}
\]

Since none of the given options directly matches with \( 2y^2 \sqrt[3]{2x} \), it's possible that there may have been a typo or misunderstanding in the options provided.

Please double-check the options to ensure there are no mistakes, or let me know if there are any clarifications on the format of the result you’re looking for.

Answer 3

To simplify the expression \(-\sqrt{2} + \sqrt{8} - \sqrt{320}\), we need to simplify the square roots involved.

1. **Simplify \(\sqrt{8}\):**
\[
\sqrt{8} = \sqrt{4 \cdot 2} = \sqrt{4} \cdot \sqrt{2} = 2\sqrt{2}
\]

2. **Simplify \(\sqrt{320}\):**
\[
\sqrt{320} = \sqrt{64 \cdot 5} = \sqrt{64} \cdot \sqrt{5} = 8\sqrt{5}
\]

Now we can substitute these simplified radicals back into the expression:
\[
-\sqrt{2} + 2\sqrt{2} - 8\sqrt{5}
\]

Next, combine the like terms:
\[
(-\sqrt{2} + 2\sqrt{2}) = (2 - 1)\sqrt{2} = \sqrt{2}
\]

Thus, the expression simplifies to:
\[
\sqrt{2} - 8\sqrt{5}
\]

Now, let's look at your response options. Unfortunately, none of the given options exactly match \(\sqrt{2} - 8\sqrt{5}\). Let’s verify the structure of our expression:

The final simplified result is:

**\(\sqrt{2} - 8\sqrt{5}\)**
