If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x in (-oo:+oo)
X = (1/4)*x^16 // - (1/4)*x^16
X-((1/4)*x^16) = 0
X+(-1/4)*x^16 = 0
-1/4*x^16 = -X // : -1/4
x^16 = 4*X
x^16 = 4*X // ^ 1/16
abs(x) = 4^(1/16)*X^(1/16)
x = 4^(1/16)*X^(1/16) or x = -(4^(1/16)*X^(1/16))
x in { 4^(1/16)*X^(1/16), -(4^(1/16)*X^(1/16)) }
