## Elementary Algebra

Using the definition of fractional exponents, we know that $x^\frac{1}{3}=\sqrt[3] x$. Written in words, this agebraic statement says that $\text{a number,}\;x,\;\text{raised to the 3rd power is equal to the cubed root of }\;x$. Therefore, with an exponent of $\frac{1}{3}$, we need to find the cubed root of the number.
