this is so easy
i^1 = i

Yes, but can you simplify them instead of answering them?

You can answer them too, if you like.

we do, i = √(-1)

why?

Hmm o_O how do you do the ones with massive powers?

thanks saudi_boy, that's quite clear and a lot simpler than my explanation

Answer,,

1.       i

2.       -i

3.       i^o=  1

4.       i^19 = i^3    =    -i

5.       1

6.       1 - i

7.        i^18 + i^13  =  i^2 + i^1    =   -1 +i

8.        1

9.         i - 1

10.        i^29 + i^14 =    i^1 + i^2 =      -i

11.         i^23 = i^3     = -i

12.         1

13.          i + 1

14.           1

15.            1

16.            -1

17.             0

18.            1
