Find the 8th roots of 3i-3<br> Urgent...please help!!!!
m_a_m_a [10]
z=-3+3i=3(-1+i)=3\left(\sqrt2e^{i3\pi/4}\right)=3\sqrt2e^{i3\pi/4}

Let z=w^8. Then the eight roots of z are

w=\left(3\sqrt2e^{i3\pi/4}\right)^{1/8}
w=3^{1/8}2^{1/16}}e^{i(3\pi/4+2\pi k)/8}

where k=0,1,\ldots,7. So the eighth roots are

w=\begin{cases}3^{1/8}2^{1/16}e^{i3\pi/32}&\text{for }k=0\\\\3^{1/8}2^{1/16}e^{i11\pi/32}&\text{for }k=1\\\\3^{1/8}2^{1/16}e^{i19\pi/32}&\text{for }k=2\\\\3^{1/8}2^{1/16}e^{i27\pi/32}&\text{for }k=3\\\\3^{1/8}2^{1/16}e^{i35\pi/32}&\text{for }k=4\\\\3^{1/8}2^{1/16}e^{i43\pi/32}&\text{for }k=5\\\\3^{1/8}2^{1/16}e^{i51\pi/32}&\text{for }k=6\\\\3^{1/8}2^{1/16}e^{i59\pi/32}&\text{for }k=7\end{cases}

A first number plus twice a second number is 5.twice the first number plus the second totals 31.find
givi [52]
So if I understand this correctly, this would look something like this:


A first number

let's call it x

 plus twice a second number

let's call the second number y:

x+2y=5

 is 5.

this means that x=5-2y!


twice the first number plus the second totals 31.

2x+y=31

from the last one, i know that y=31-2x

and i can insert it into the first equation:

So i know that x=5-2y

and that

2x+y=31
i will substitute x here

2(5-2y)+y=31

remove the bracket

10-4y+y=31


10-3y=31

remove 10 from both sides

-3y=21

then

y=-7

and
x=5-2(-7)=5+14=19
