Solution for 3/x^6=129 equation: 


D( x )

x^6 = 0

x^6 = 0

x^6 = 0

1*x^6 = 0 // : 1

x^6 = 0

x = 0

x in (-oo:0) U (0:+oo)

3/(x^6) = 129 // - 129

3/(x^6)-129 = 0

3*x^-6 = 129 // : 3

x^-6 = 43

-6 < 0

1/(x^6) = 43 // * x^6

1 = 43*x^6 // : 43

1/43 = x^6

x^6 = 1/43 // ^ 1/6

abs(x) = (1/43)^(1/6)

x = (1/43)^(1/6) or x = -(1/43)^(1/6)

x in { (1/43)^(1/6), -(1/43)^(1/6) }
