6^5x=20 round to the nearest ten-thousands

I think you're saying that the exponent is (5x), and the equation is

6⁵ˣ = 20 .

IF so, then . . .

Take the log of each side:  5x·log(6) = log(20)

Divide each side by  log(6) :  5x = log(20) / log(6)

Divide each side by  5 :      x = 0.2 log(20) / log(6)

x = 0.2 · (1.30103) / (0.77815)

x = 0.33439
