Solution

To simplify the given radical expression, we need to rewrite it in the required form. The expression is:

64x143\sqrt[3]{64x^{14}}

Step 1: Break the expression inside the radical into factors

64x14=(64)(x14).64x^{14} = (64) \cdot (x^{14}).

Step 2: Simplify the cube root of 6464

Since 64=4364 = 4^3, we have: 643=4.\sqrt[3]{64} = 4.

Step 3: Simplify the cube root of x14x^{14}

Using the property of exponents for cube roots, x143=x14/3\sqrt[3]{x^{14}} = x^{14/3}. Break this into: x14/3=x4x2/3,x^{14/3} = x^4 \cdot x^{2/3}, where x4x^4 is the integer part, and x2/3x^{2/3} remains under the cube root.

Step 4: Combine terms

The simplified form of the expression is: 4x4x23.4x^4 \sqrt[3]{x^2}.

Step 5: Apply absolute value if needed

When dealing with even powers and cube roots, we don't typically need the absolute value for the root part. Hence: [ A = 4|x^4|, \quad B = x^2, \quad \text{and } A\sqrt[3]{B} = 4x^4\sqrt[3]{x^2}. ]

Final Answer:

4x4x23\boxed{4x^4 \sqrt[3]{x^2}}
