Hello here is a solution :
<span>x² − 8x − 4 = 0.
</span><span>quadratic equation ax²+bx+c = 0 when : a=1 and b= -8 and c = -4
discriminant : d = b²-4ac d= (-8)²-4(1)(-4) =64+16 =70
x= (-b-rot(d))/2a </span>x'= (-b+rot(d))/2a .......conrinu
Answer:
Option A, 2^(1/6)
Step-by-step explanation:
<u> is same as 2^(1/2)</u>
<u />![\sqrt[3]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%7D)
<u> is same as 2^(1/3)</u>
<u />
2^(1/6)
Answer: Option A, 2^(1/6)
We know that
The formula to <span>find the sum of the interior angles of a regular polygon is
</span>(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides
the answer is
6 sides
