thank you

You're welcome!

To solve both of these expressions, you need to understand the concept of exponents and the order of operations.

In mathematics, an exponent tells you how many times a number (base) should be multiplied by itself. The notation for exponents is a superscript number after the base. For example, "x^2" means x multiplied by itself, or x squared.

Now, let's solve the expressions.

1. -5^2:
First, we need to calculate the exponent before performing any other operations. In this case, the exponent is 2. So, we square -5, which means multiplying -5 by itself.
-5^2 = -5 × -5 = 25

Therefore, -5^2 is equal to 25.

2. -(-5)^2:
Here, we have parentheses surrounding -5. According to the order of operations (PEMDAS/BODMAS), we should perform the operation inside the parentheses first.
(-5)^2 means -5 multiplied by itself.
(-5)^2 = -5 × -5 = 25

However, there is a negative sign in front of the expression. When we have a negative sign outside the parentheses, we need to apply it after performing the exponentiation.
So, -(-5)^2 = -1 × 25 = -25

Therefore, -(-5)^2 is equal to -25.
