I didn’t begin by dividing by 36^x to arrive at same quadratic

You spent the 1st three lines trying to have 1 on one side of the equation...while you had it since the start: 1^x=1

lg[(1+V5)/2]:lg6, if x is a real number. NOTE. Other roots are complex numbers.

Hi, The shown solution is not correct. If x= 0,26857 , the initial equation give the same result for both sides, i.e. this is the correct solution.

I use u=6^x u²-u-1 = 0 u = (1±√5)/2 = φ or -1/φ, φ = (1+√5)/2, the golden ratio real solution: x = log₆(φ) non-real solution: x = ln(-1/φ)/ln(6) = -log₆(φ) + (2n+1)πi/ln(6)
