The value of (—5)² is 25.
Let's break it down mathematically:
When you square a number, you multiply it by itself. So:
The result of multiplying two negative numbers is positive, which gives us 25.
- A) -25: This is incorrect because squaring a negative number results in a positive value.
- B) (-25)²: This would give a different answer. The expression (-25)² would be 625, not 25.
- C) 5: This is incorrect, as squaring -5 results in a positive value, not a positive 5.
Thus, the correct answer is D) 25.
