A. 4x^3square root of 2

B. 8x^3

C. 4x square root of 2

D. 16x^3

1 answer

To simplify the expression \(\sqrt{32x^6}\), we can break it down into smaller parts.

  1. Start by factoring \(32\): \[ 32 = 16 \cdot 2 = 4^2 \cdot 2 \]

  2. For \(x^6\), we know that: \[ x^6 = (x^3)^2 \]

  3. Now we can rewrite the expression: \[ \sqrt{32x^6} = \sqrt{32} \cdot \sqrt{x^6} \]

  4. Now, evaluate \(\sqrt{32}\) and \(\sqrt{x^6}\): \[ \sqrt{32} = \sqrt{16 \cdot 2} = \sqrt{16} \cdot \sqrt{2} = 4\sqrt{2} \] \[ \sqrt{x^6} = x^{6/2} = x^3 \]

  5. Putting it all together: \[ \sqrt{32x^6} = 4\sqrt{2} \cdot x^3 = 4x^3\sqrt{2} \]

Therefore, the expression equivalent to \(\sqrt{32x^6}\) is:

A. \(4x^3\sqrt{2}\).
