Solution for 2/3k=28x4/9 equation: 


x in (-oo:+oo)

(2/3)*k = (28*x^4)/9 // - (28*x^4)/9

(2/3)*k-((28*x^4)/9) = 0

(2/3)*k+(-28/9)*x^4 = 0

-28/9*x^4 = -(2/3*k) // : -28/9

x^4 = 3/14*k

x^4 = 3/14*k // ^ 1/4

abs(x) = (3/14)^(1/4)*k^(1/4)

x = (3/14)^(1/4)*k^(1/4) or x = -((3/14)^(1/4)*k^(1/4))

x in { (3/14)^(1/4)*k^(1/4), -((3/14)^(1/4)*k^(1/4)) }
