ln(4*x)/6-ln(3*x) = 0
ln(1*(4*x)^(1/6))-ln(3*x) = 0
ln((1*(4*x)^(1/6))/(3*x)) = 0
ln(((4*x)^(1/6))/(3*x)) = 0
ln(((4*x)^(1/6))/(3*x)) = ln(e^0)
((4*x)^(1/6))/(3*x) = e^0
((4*x)^(1/6))/(3*x)-e^0 = 0
((4^(1/6))/3)*x^(-5/6) = 1 // : (4^(1/6))/3
x^(-5/6) = 3*4^(-1/6)
-5/6 < 0
1/(x^(5/6)) = 3*4^(-1/6) // * x^(5/6)
1 = 3*4^(-1/6)*x^(5/6) // : 3*4^(-1/6)
1/(3*4^(-1/6)) = x^(5/6)
x^(5/6) = 1/(3*4^(-1/6)) // ^ 6
x^5 = 4/729 // ^ 1/5
x = (4/729)^(1/5)
x = (4/729)^(1/5)
