WebWell, first you can use the property from this video to convert the left side, to get log ( log (x) / log (3) ) = log (2). Then replace both side with 10 raised to the power of each side, to get log (x)/log (3) = 2. Then multiply through by log (3) to get log (x) = 2*log (3). Then use the multiplication property from the prior video to convert ...
