Answer:
4-9=-5
Step-by-step explanation:
do the work you get that
Let r(cos O + i sin O) be a cube root of 125(cos 288 + i sin 288)
then
r^3(cos O + i sin O)^3 = 125(cos 288 + i sin 28)
so r^3 = 125 and cos 3O + i sin 3O = cos 288 + i sin 288
so r = 5 and 3O = 288 + 360p and O = 96 + 120p
so one cube root is 5 (cos 96 + i sin 96)
Im a little rusty at this stuff Its been a long time.
Im not sure of the other 2 roots
sorry cant help you any more
You should expect
5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's
1/9 45 times, or 1/9(45).

1*45 is 45
9*1 is 9.
45/9 is
5.
