◆ 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.
4(2x-5)
8x-20
it is equal to 8x-20 because you simplify it and it turns into that.

22+33+44+55+66+77+88+99=484
Answer:
10/11
Step-by-step explanation:
The fractions already have like denominators so you just add the numerators as there is no need to find the LCM but just in case
The answer to that equation is 7938
