Solution for ln(x^7/3*x^2*x^5) equation: 


D( x )

x^2*x^5*((x^7)/3) <= 0

x^2*x^5*((x^7)/3) <= 0

x^2*x^5*((x^7)/3) <= 0

1/3*x^14 <= 0

1/3*x^14 <= 0 // : 1/3

x^14 <= 0/1/3

x^14 <= 0

x in <0:0>

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

ln(x^2*x^5*((x^7)/3)) = 0

ln(x^2*x^5*((x^7)/3)) = ln(e^0)

x^2*x^5*((x^7)/3) = e^0

x^2*x^5*((x^7)/3)-e^0 = 0

1/3*x^14 = 1 // : 1/3

x^14 = 3

x^14 = 3 // ^ 1/14

abs(x) = 3^(1/14)

x = 3^(1/14) or x = -3^(1/14)

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