1. The problem asks to find the value of a negative number raised to a positive power, specifically $-(9^2)$. 2. First, calculate the exponentiation inside the parentheses: $9^2 = 81$. 3. Then apply the negative sign outside the parentheses: $-(9^2) = -81$. 4. So the value of $-(9^2)$ is $-81$. 5. Among the options given, the correct answer is $-81$.
