Question: how do I solve the problem ln x +ln 2 = 2 ln 6? 

Answer: Take e^x of everything. You get the following equation:\n\nx + 2 = 6^2\n\nx = 34\n\nLn and e^x are inverse operations of each other, just like log and 10^x. The 2*ln6 expression, after the e^x treatment, becomes 6^2, because the constant in front of the ln gets popped into an exponent.
