Powers of i :
To determine the value of i raised to a power greater than two, we rewrite the term using exponent rules.Remember that i2 = -1 and i4 = 1. Therefore, any exponent of i that is a multiple of four will equal one; any even exponent not divisible by four will equal negative one. Also, negative exponents indicate a reciprocal of the base; if i is in the denominator, it will need to be rationalized.
