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
Your answer is either A or D
Answer:
There are 2 ways, since we'd chosen 2 fruits
PROBABILITY:
(
= 
) or 
METHOD:
In the 2 fruits we took both of them might be pears either maybe one of them can be a pear. The same is possible with the other fruit.

A. Or B.
I picked this in one of my questions and I don’t remember which specific one but the one or other should be correct.
Answer:
Step-by-step explanation:
The degree of polynomial is the sum of exponents of the variables involved in the expression,hence the given degree is
2+3=5,so 5 is the degree of the polynomial.
