Did it in my head before watching. x = 1/2. 9 to the 0.5 power = 3. 9 to the 1st = 9. 9 x 3 = 27. 3 to the (2x0.5 + 1) => 3 to the 2nd = 9. 27 + 9 = 36.
9^(x+1)+3^(2x+1)=36 x=1/2=0.5 x=1/2+(Log[3,0.004115226337448559670781893 recurring e^(2π)]+5)i= 0.5+(Log[3,0.004115226337448559670781893 recurring e^(2π)]+5)i
