Simplifying x3\sqrt{x^3}

To simplify the radical x3\sqrt{x^3}, find the largest perfect square factor within the variable radicand. Rewrite the radicand as the product of this largest even power and the remaining variable: x2x\sqrt{x^2 \cdot x}. Apply the Product Property to split the expression into the product of two radicals: x2x\sqrt{x^2} \cdot \sqrt{x}. Because the index of the square root is even, evaluating x2\sqrt{x^2} requires an absolute value sign to ensure the result is non-negative, yielding x|x|. Multiplying this by the remaining square root produces the final simplified form xx|x|\sqrt{x}.
