Answer

The expression we need to evaluate is $-100 - (-5)^3$. The expression is evaluated to $25$.

Work Step by Step

First, let's translate this problem into an algebraic expression we can simplify: Cube $-5$ means $(-5)^3$. We subtract this expression from $-100$ to get the following expression: $$-100 - (-5)^3$$ According to order of operations, let's evaluate the exponent first: $$-100 - (-125)$$ When we subtract a negative number, this means that we add the number: $$-100 + 125$$ Let's do the addition: $$25$$ The expression is evaluated to $25$.
