Question

WILL GIVE BRAINLEST ANSWER IF DONE IN 24 HOURS Find the fourth roots of 256(cos 240° + i sin 240°).

Answer 1

Answer:

Hello There!

`~~~~~~~~~~~~~~~~~~~~`

4th root of 256 is 4, and 240/4 = 60, and 360/4 = 90, so the 4 roots are

4(cos 60 + i sin 60)

4(cos 150 + i sin 150)

4(cos 240 + i sin 240)

4(cos 330 + i sin 330)

Hope this helped you. Brainliest would be nice!
