Question:

How do I solve these?
Any help would be great. i^23 i^70 i^82 -Thanks

Answers:

A-Best: i to the power of an odd number is i i to the power of an even number is 1 i^23 = i i^70 = 1 i^82 = 1  

A: Well my calculator that can work in imaginary numbers just gives math error so no hope there. I have studied this yet but..... i= SQRT(-1) Sqrt(-1)^2= -1 =i^2 Sqrt(-1)^3= 1 = i^3 Sqrt(-1)^4= -1 =i^4 so following this sequence every odd power equals a +1 and every even power gives -1. So i^23 equals 1 i^50 equals -1 i^82 equals -1 I'm not sure but i don't see whats wrong with this.....
