Question

Medal to helper!!

If x^n=1 for all real numbers x(= crossed equals sign)0, then what does n equal?

Answer 1

By definition, x^0 = 1. The variable x can be any real number but 0.

In other words, we can't say 0^0 = 1, but we can say something like 2^0 = 1 or 3^0 = 1, etc.

Answer 2

Well the choices are:
a. -1
b. 1
c. 0
d. x

Would it be B or can it go into negatives?

Answer 3

compare x^n = 1 with what I wrote: x^0 = 1
