Best ResponseYou've already chosen the best response.0Find the complex fourth roots of 81(cos(3pi/8)+isin(3pi/8)) A: Find the fourth root of 81. B: Divide the angle in the problem by 4 to find the first argument. C: Use the fact that adding 2pi to the angle 3pi/8 produces the same effective angle to generate the other three possible angles for the fourth roots. Be sure that your angles lie between 0 and 2pi. D: Find all 4 of the fourth roots of 81(cos(3pi/8)+isin(3pi/8)) Express your answers in polar (r(cos(theta)+isin(theta))) form.
