Find the cube roots of 27(cos 327° + i sin 327° ). Write the answer in trigonometric form.

3(cos 109° + i sin 109°)

3(cos 229° + i sin 229°)

3(cos 349° + i sin 349°)

Step-by-step explanation:

27(cos 327° + i sin 327°)

Modulus: 27^⅓ = 3

Arguments:

327/3 = 109

(327+360)/3 = 229

(327+2(360))/3 = 347

Cube roots are:

3(cos 109° + i sin 109°)

3(cos 229° + i sin 229°)

3(cos 349° + i sin 349°)

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
