Correct Answer:
B. 1
Correct answer: 1. A negative one raised to an even power equals 1, and 300 is even.
Background: (−1)ⁿ = 1 if n is even and −1 if n is odd.
- −1: −1 would result from an odd power.
- 0: 0 cannot result from raising −1 to a power.
- 300: 300 is not the value of this expression.
Did you know? Pairs of −1 multiply to give +1.
Memory trick: Even power → +1.
