Solve the Nested Expression: -|-x³| Step by Step

The expression has an absolute value and a negative sign outside of the absolute value. When you take the absolute value of $-x^3$, it results in $|x^3|$, which is $x^3$ assuming$x$ is a real number. The negative sign outside the absolute value inverts it back to $-x^3$. Thus, the correct interpretation of the original expression $-\left|-x^3\right|$ is $-x^3$.
