(-5^2) = -25

right ?

(-5)^2 = 25, but -(5^2) is -25.

What you have written is ambiguous.

no , my problem is :

(-5^2)

Your problem is ambiguous. You have to make clear what is being squared: -5 or 5.

No, the result of (-5^2) is actually 25, not -25.

To understand why, let's break it down step by step:

1. The exponentiation operation, denoted by the "^" symbol, is performed first. So, the expression becomes -(5^2).

2. Next, we calculate the value of 5^2. The exponent 2 means that we multiply 5 by itself: 5^2 = 5 * 5 = 25.

3. Finally, we apply the negative sign in front of the result, giving us -(25) = -25.

Therefore, the correct answer is -25.
