Answer

False

Work Step by Step

We will solve the equation to see what its solution is: Step 1: $\sqrt[3] {x+2}=-2$ Step 2: Raising each side of the equation to the power of $3$ and simplifying, we find: $(\sqrt[3] {x+2})^{3}=(-2)^{3}$ $x+2=-8$ Step 3: Solving the equation, we find: $x+2=-8$ $x=-8-2$ $x=-10$ Therefore, the solution set of the equation is {$-10$}, which means that the question statement is false.
