Answer:

z^{5} =  - 12 + 316 i

Step-by-step explanation:

Given that -

z = 3 + i

<em>z^{2} = ( 3 + i )^{2}</em>

<em>z^{2} = 9 + i^{2} + 6 i</em>

<em>z^{2} = 9 - 1 + 6 i</em>

z^{2} = 8 + 6 i

<em>z^{3} = z^{2} × z</em>

<em>z^{3} = ( 8 + 6 i ) × ( 3 + i )</em>

<em>z^{3} = 24 + 8 i + 18 i + 6 i²</em>

<em>z^{3} = 24 + 26 i - 6</em>

z^{3} = 18 + 26 i

z^{5} = z^{2} × z^{3}

<em>z^{5} = ( 8 + 6 i ) × ( 18 + 26 i )</em>

<em>z^{5} = 144 + 208 i + 108 i + 156 i²</em>

<em>z^{5} = 144 + 316 i -156</em>

z^{5} =  - 12 + 316 i

The value of x is 1.25 or 1 1/4

Explanation
==============================
275x=500-125x 
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
