To simplify the radical \( \sqrt[3]{16xy^6} \), we can start by breaking it down into its prime factors.

  1. Factor out the numbers and variables:
    • \( 16 = 2^4 \)
    • \( x \) remains \( x \)
    • \( y^6 \) can be written as \( (y^2)^3 \)

So we rewrite the expression: \[ \sqrt[3]{16xy^6} = \sqrt[3]{2^4 \cdot x \cdot (y^2)^3} \]

  1. Split the cube root: \[ \sqrt[3]{2^4} \cdot \sqrt[3]{x} \cdot \sqrt[3]{(y^2)^3} \] \[ = \sqrt[3]{2^4} \cdot \sqrt[3]{x} \cdot y^2 \]

  2. Simplify \( \sqrt[3]{2^4} \):

    • \( 2^4 = 2^3 \cdot 2 = 8 \cdot 2 \)
    • Therefore, \( \sqrt[3]{2^4} = \sqrt[3]{2^3 \cdot 2} = \sqrt[3]{2^3} \cdot \sqrt[3]{2} = 2 \cdot \sqrt[3]{2} \)

So now we have: \[ 2 \cdot \sqrt[3]{2} \cdot y^2 \cdot \sqrt[3]{x} \]

Combining these gives: \[ 2y^2 \sqrt[3]{2x} \]

Now we check the options provided:

  • \( 2xy^2 \sqrt{2} \)
  • \( 8y^2 \sqrt{2/x} \)
  • \( \frac{2y^2}{2x} \)
  • \( 4y^2 \sqrt{x} \)
  • \( \frac{4y^2}{x} \)

None of the provided options exactly match the simplified form \( 2y^2 \sqrt[3]{2x} \). Please double-check the options or the original expression for a possible error or a different configuration!
