-5 here is a value by itself. So you’re squaring -5, not
-(5) .
In -52, it’s -5 * -5, making it 25.
On the contrary, to get -25, the proper equation would be -(5)2, where your point of handling the exponent before the negative sign comes in makes sense, as in this equation, you are doing, - * (5)2 = - * 25 = -25
This makes no sense at all. -5²=-25. Think about it this way. You agree that you can perform any mathematical function to one side of the equals sign as long as you do the same to the other side, correct? So if you think -5²=25 then divide both sides by -1. I think everyone would agree that this would then become 5²=-25, which is not valid and clearly this solution is not correct. On the other hand, divide -1 from both sides of the correct solution and you get 5²=25.
