D( x )
x^5 = 0
x^5 = 0
x^5 = 0
1*x^5 = 0 // : 1
x^5 = 0
x = 0
x in (-oo:0) U (0:+oo)
z = (5*x^4*y)/(x^5) // - (5*x^4*y)/(x^5)
z-((5*x^4*y)/(x^5)) = 0
z-5*x^-1*y = 0
-5*x^-1*y = -z // : -5*y
x^-1 = (1/5)*y^-1*z
-1 < 0
1/(x^1) = (1/5)*y^-1*z // * x^1
1 = (1/5)*x^1*y^-1*z // : (1/5)*y^-1*z
5*y*z^-1 = x^1
x = 5*y*z^-1
x = 5*y*z^-1
