Is the following statement true or false?
For every integer n, if n is prime then (-1)^n = -1.
Which of the choices below answers the question? (Select all that apply.)
The statement is true because all prime numbers are odd, and -1 raised to any odd power is -1.
The statement is true. For instance, when n = 3, (-1)^n = (-1)^3 = -1.
The statement is false because when n = 0, (-1)^n = (-1)^0 = 1.
The statement is false because not every prime number is odd, and -1 raised to an even power is 1.
