Hey
Mattchance666,
Lets solve this equation together,
The question we are enquiring is : What is the value of i ^20+1?
To solve this equation: we have to use the Power Reduction Rule.
Where I^n=I{n mod 4}<span>
</span>In this case: <span>I^20 = I^{5*4+0}=I^0</span>
1 + 1 = 2
Hope this helps,

15) x = 8, 
16) x = 9,

17) x = 6,

<u>Step-by-step explanation:</u>
15x³ - 119x² - 10x + 16 = 0

So, the possible rational roots are: +/- 
Use synthetic division with each one until you find a remainder of zero. I am not going to go through each one because it is too time consuming, however, the first one that works is x = 8
(x - 8)(15x² + x - 2)
Next, factor 15x² + x - 2 using any method
(x - 8)(3x - 1)(5x + 2)
Now, solve for x.
x = 8, x =
, x =

For #16 & 17, follow the same process as above.
