Your question is very vague.
If you are talking about the number 1,
Any number or variable raised to 1 is the number or the variable itself.
x^1 = 1
If you are talking about the complex number i =√(-1) , then the answer is yes but to understand more about that stuff, you need a lot more knowledge in trigonometry and logarithms.
I will provide the solution below.
Consider a real number A, and take it to the power i. If our system of complex numbers is to be consistent, then A^i must be a complex number; in other words, there must be two real numbers x and y, which depend on A, such that:
A^i = e^(i*lnA)
