Answer:
x=-1
Step-by-step explanation:
4(x−3)=8(x−1)
Distribute
4x - 12 = 8x -8
Subtract 4x
4x-12 -4x= 8x-8-4x
-12 = 4x-8
Add 8 to each side
-12+8 = 4x-8+8
-4 = 4x
Divide by 4
-4/4 = 4x/4
-1 =x
Answer:
There are seven seventh roots of unity, e2πki7 , all on the unit circle, r=1 above.
The first one is at θ=2π7=360∘7=5137 ∘ , and there are others at 4π7,6π7,8π7,10π7,12π7 and of course at 0 radians, i.e. unity itself.
How to find?
There are 4 fourth roots of unity and they are 1, i,−1 and−i
Each of the roots of unity can be found by changing the value of k k k in the expression e 2 k π i / n e^{2k\pi i/n} e2kπi/n. By Euler's formula, e 2 π i = cos ( 2 π ) + i sin ( 2 π ) = 1.
42+35 is 77
7(6+5) is 77 so yes
