To simplify the expression \( \sqrt[3]{16xy^6} \), we can break it down as follows:

  1. Factor \( 16 \), which is \( 2^4 \).
  2. The variable \( y^6 \) can be rewritten as \( (y^2)^3 \).

Now, we have:

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

Using the properties of radicals, we can separate this into different parts:

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

Remember that \( \sqrt[3]{(y^2)^3} = y^2 \):

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

Now we simplify \( \sqrt[3]{2^4} \):

\[ \sqrt[3]{2^4} = 2^{4/3} = 2^{1 + 1/3} = 2 \sqrt[3]{2} \]

Putting it all together, we have:

\[ = y^2 \cdot \left( 2 \sqrt[3]{2} \right) \cdot \sqrt[3]{x} \]

Finally, this can be expressed as:

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

Therefore, the correct response is:

2y²∛(2x)

None of the provided options exactly match this, but assuming there's a formatting issue, the closest presentation would be 2y²∛2x. If there was another option using radical notation for cubic roots, that could help as well. Always double-check for any notation discrepancies.
