Best ResponseYou've already chosen the best response.1ln x + ln6x = 8 ln(x*(6x)) = 8 > Sum of logs is log of product ln(6x^2) = 8 e^8 = 6 x^2 > Definition of log e^8/6 = x^2 x^2 = (e^8)/6 x = (e^4) / Sqrt (6) > Square root of both sides

Best ResponseYou've already chosen the best response.1x = (e^4) / Sqrt (6) is the exact answer. You can approximate for e and Sqrt(6) if that is what you mean.
