◆ COMPLEX NUMBERS ◆
125 ( cos 288 + i sin 288 ) can be written as -
125.e^i( 288)
125.e^i( 288 +360 )
125.e^i( 288+ 720)
[ As , multiples of 360 can be added to an angle without changing any trigonometric functions or sign ]
To find the cube root , take the cube root of above 3 expressions ,
We get -
5 e^( i 96 )
5 e^( i 216 )
5 e^( i 336 )
Now using Euler's formula , We rewrite above as -
5 ( cos 96 + i sin 96 )
5(c os 216 + i sin 216 )
5 ( cos 336 + i sin 336 ) Ans.

Answer:
The amount that came is 
Step-by-step explanation:
The computation is shown below:
According to the question, it is mentioned that
Multiply 4 by 
First open the equation in a fraction it would be 
Now multiplied the above fraction by a 4
That gives the result of
Hence, the amount that came is
We simply multiply the 4 with the given fraction
Thus the above represents the simplest form of the fraction
