Recognize that the expression is the cube root of \(x^3\), which can be written as \(\sqrt[3]{x^3}\).
Recall the property of radicals and exponents: \(\sqrt[n]{a^m} = a^{\frac{m}{n}}\). Applying this, rewrite the expression as \(x^{\frac{3}{3}}\).
Simplify the exponent \(\frac{3}{3}\) to 1, so the expression becomes \(x^1\).
Understand that \(x^1\) is simply \(x\), so the cube root of \(x^3\) simplifies to \(x\).
Note that this simplification holds for all real numbers \(x\), considering the cube root function is defined for all real numbers.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Cube Roots
The cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 8 is 2 because 2³ = 8. Cube roots can be positive, negative, or zero.
Exponents indicate how many times a base is multiplied by itself. Key properties include that (a^m)^n = a^(m*n) and that roots can be expressed as fractional exponents, such as the cube root of x being x^(1/3).
Simplifying radicals involves rewriting expressions to their simplest form. For cube roots, this means recognizing when the radicand is a perfect cube, allowing the root and exponent to cancel out, such as ∛(x³) = x.
