D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
4*x^3-(1/x) = 0
4*x^3-x^-1 = 0
4*x^3-x^-1 = 0
x^-1*(4*x^4-1) = 0
4*x^4 = 1 // : 4
x^4 = 1/4
x^4 = 1/4 // ^ 1/4
abs(x) = (1/4)^(1/4)
x = (1/4)^(1/4) or x = -(1/4)^(1/4)
1/x = 0
1*x^-1 = 0 // : 1
x^-1 = 0
x należy do O
x in { (1/4)^(1/4), -(1/4)^(1/4) }
