x in <0:0>

x in (0:+oo)

ln(x^(5/2))+ln(9*x) = 0

5/2*ln(x)+ln(9*x) = 0

ln(1*x^(5/2))+ln(9*x) = 0

ln(1*9*x*x^(5/2)) = 0

ln(9*x*x^(5/2)) = 0

ln(9*x*x^(5/2)) = ln(e^0)

9*x*x^(5/2) = e^0

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

9*x^(7/2) = 1 // : 9

x^(7/2) = 1/9

x^(7/2) = 1/9 // ^ 2

x^7 = 1/81 // ^ 1/7

x = (1/81)^(1/7)

x = (1/81)^(1/7)
