To simplify \(\sqrt{2x^9}\), we can break it down as follows:

  1. Separate the square root into components: \[ \sqrt{2x^9} = \sqrt{2} \cdot \sqrt{x^9} \]

  2. Simplify \(\sqrt{x^9}\): \[ \sqrt{x^9} = \sqrt{x^{8} \cdot x^1} = \sqrt{x^{8}} \cdot \sqrt{x} = x^4 \cdot \sqrt{x} \]

  3. Rewrite the expression: \[ \sqrt{2x^9} = \sqrt{2} \cdot x^4 \cdot \sqrt{x} = x^4 \sqrt{2x} \]

So, the simplified form of \(\sqrt{2x^9}\) is: \[ x^4 \sqrt{2x} \]

Now let's check the provided multiple choice answers to see which corresponds to our simplification:

  • \( x^5 \sqrt{2x} \)
  • \( 2x \)
  • \( 2x^4 \sqrt{2x} \)
  • \( x^4 \sqrt{2x} \)

The correct answer is: \[ x^4 \sqrt{2x} \]
