12 POINTS<br>Simplify i38. <br> i <br> −1 <br> −i <br> 1
Karolina [17]
Are you sure you've copied down the original problem exactly as given?  i38 = 38i can't be simplified.  Perhaps you meant i^38, which is a different matter.

Note that i^38 = i^32 * I^4 * I^2.

Note that i^0, i^4, i^8, etc., all equal 1.  Therefore,

i^38 = (1)(1)i^2 = 1*(-1) = -1 (answer)
