Final answer:
To evaluate -(5-4)(5^2), we subtract 4 from 5, square 5 to get 25, multiply the results to get 25, and then apply the negative sign to get the final answer, which is -25.
Step-by-step explanation:
To evaluate the expression -(5-4)(5^2), we need to perform the operations step by step.
- First, we calculate the difference inside the parentheses: 5 - 4 = 1.
- Next, we find the square of 5, which is 5^2 = 25.
- Now, we multiply the result from the first step by the square of 5: 1 * 25 = 25.
- Finally, we add the negative sign in front of the parentheses to the product: -(25) = -25.
Therefore, the correct evaluation of the expression is -25, which corresponds to option D.
