A-Best: i squared equals -1. Therefore it reduces to -1 to the 13th power which equals-1
A: 26 is even, and i raised to an even power is -1
Thus i^26 = -1
A: you could write it as ( (i)^2 )^13 = -1
i^2 = -1, and (-1)^13 = -1 since it raised to an odd power
A: here's an easy way:
divide 26 by 4.
if it ends with .25 its -1
.5 its i
.75 its -i
no decimal its 1
i THINK.
