    3^x+(3^x)²=(3^x)³
    (3^x)[(3^x)²-(3^x)-1]=0
    x=0 or 3^x=ß, golden ratio
    =½[1±sqrt(5)]
    x=[log(ß)]/log(3)

    Lack an approximate result in a normal digits. Without any counting and calculating I assessed x as ca 0,7, in 10 sec.

      x = log((√5 + 1)/2)/log(3)
      ≈ 0.4380178794859...
