Answer

$(-1, 0) \cup (1, +\infty)$

Work Step by Step

Graph $y_1 =x^{1/3}$ (the orange graph) and $y_2=x$ (the purple graph) on the same coordinate plane. (refer to the attached image below for the graph) The solution to the given inequality is the set of x-values for which $y_1 \lt y_2$. Notice that $y_1$ (the orange graph) is less than $y_2$ in the following intervals: $(-1, 0)$ and $(1, +\infty)$ Thus, the solution to the given inequality is: $(-1, 0) \cup (1, +\infty)$
