text: how do i solve the problem ln x +ln 2 = 2 ln 6?   take e^x of everything. you get the following equation:  x + 2 = 6^2  x = 34  ln 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.
